&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;El cálculo de las raíces de las &lt;a href=&quot;http://es.wikipedia.org/wiki/Ecuaci%C3%B3n&quot; target=&quot;_blank&quot;&gt;ecuaciones&lt;/a&gt; es un problema que
se ha tenido que enfrentar par eso sean elaborado diversos métodos ya que al
determinar las raíces de una ecuación también lograremos máximos y mínimos,
valores propios de &lt;a href=&quot;http://es.wikipedia.org/wiki/Matriz_(matem%C3%A1ticas)&quot; target=&quot;_blank&quot;&gt;matrices&lt;/a&gt;, resolver sistemas de ecuaciones lineales y
diferenciales, etc.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Un método consiste en graficar la &lt;a href=&quot;http://es.wikipedia.org/wiki/Funci%C3%B3n_matem%C3%A1tica&quot; target=&quot;_blank&quot;&gt;función&lt;/a&gt; y ubicar el punto
donde la grafica intercepta al eje de las abscisas o eje x. El punto ubicado x
es el valor de la raíz donde f(x)=0.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Pero el &lt;a href=&quot;http://es.wikipedia.org/wiki/Sistema_de_ecuaciones&quot; target=&quot;_blank&quot;&gt;método grafico&lt;/a&gt; no es preciso por eso de elaboro
otros métodos más efectivos capaces de ayudarnos en el campo de la ingeniería,
pues son frecuentes en áreas de diseño,&amp;nbsp;cálculos&amp;nbsp;para la optimización de recursos
y otros.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Para el estudio podemos organizar los métodos de la
siguiente manera:&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;b&gt;&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Métodos cerrados &lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Como su nombre lo dice este método encierra la función en un
intervalo donde dicha función cambia de signo para tener una raíz dentro de
este intervalo y luego empezar &amp;nbsp;reducir por
medios de &lt;a href=&quot;http://es.wikipedia.org/wiki/Algoritmo&quot; target=&quot;_blank&quot;&gt;algoritmos&lt;/a&gt; el tamaño del intervalo.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li style=&quot;text-align: justify;&quot;&gt;&lt;a href=&quot;http://metodos-numericos-matlab.blogspot.com/2012/01/teorema-de-bolzano.html&quot;&gt;&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Teorema de Bolzano&lt;/span&gt;&lt;/a&gt;&lt;/li&gt;

&lt;b&gt;&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;Métodos abiertos&lt;/span&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;span style=&quot;font-family: Verdana, sans-serif;&quot;&gt;A diferencia de los métodos cerrados estos solo necesitan un
valor inicial, pues no encierran la raíz. En algunos casos la operación &lt;a href=&quot;http://es.wikipedia.org/wiki/Divergencia_(matem%C3%A1tica)&quot; target=&quot;_blank&quot;&gt;diverge&lt;/a&gt;
(se aleja de la raíz) y otros &lt;a href=&quot;http://es.wikipedia.org/wiki/Convergencia_(desambiguaci%C3%B3n)&quot; target=&quot;_blank&quot;&gt;converge&lt;/a&gt; (se acerca a la raíz) hallando de manera
más efectiva la raíz.&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&amp;nbsp;Método de
regula falsi&amp;nbsp;(regla falsa)
o&amp;nbsp;falsa posición &amp;nbsp;es un método iterativo que a diferencia del
método de la bisección, este se basa en una visualización grafica que consiste
en unir f(a&lt;sub&gt;0&lt;/sub&gt;) y f(b&lt;sub&gt;0&lt;/sub&gt;) con una línea recta, la
intersección de esta recta con el eje de coordenadas x representa una mejor
aproximación de la raíz que por el método de la bisección, aunque no siempre es
así.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot; style=&quot;text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;

&lt;div class=&quot;MsoNormal&quot; style=&quot;background: white; line-height: 14.25pt; margin-bottom: 6.0pt; margin-left: 0cm; margin-right: 0cm; margin-top: 4.8pt;&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;El método de bisección sirve resolver
ecuaciones en una variable. Se basa en el&amp;nbsp;&lt;span style=&quot;text-decoration: none;&quot;&gt;teorema del valor
intermedio&lt;/span&gt;&amp;nbsp;(TVI), el cual establece que toda función
continua&amp;nbsp;&lt;i&gt;f&lt;/i&gt;&amp;nbsp;en un intervalo cerrado
[a,b] toma todos los valores que se hallan entre&amp;nbsp;&lt;i&gt;f&lt;/i&gt;(&lt;i&gt;a&lt;/i&gt;) y&amp;nbsp;&lt;i&gt;f&lt;/i&gt;(&lt;i&gt;b&lt;/i&gt;) si &lt;i&gt;f&lt;/i&gt;(&lt;i&gt;a&lt;/i&gt;) x&amp;nbsp;&lt;i&gt;f&lt;/i&gt;(&lt;i&gt;b&lt;/i&gt;)&amp;lt;0 entonces
existe un numero&amp;nbsp; llamado raiz “r” tal
que f(r)=0. De esta forma, se asegura la existencia de al menos una solución o raíz
de la ecuación&amp;nbsp;&lt;i&gt;f&lt;/i&gt;(x)=0. Luego el intervalo se divide en dos,
si la función cambia de signo&amp;nbsp; en uno de
los nuevos intervalos, este se vuelve a dividir y así sucesivamente hasta
obtener una aproximación adecuada.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Algoritmo&amp;nbsp; de bisección&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp;Paso 1: Usando el
teorema de Bolzano localizar los intervalos en los que podemos encontrar al
menos una raíz &lt;i&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;f&lt;/span&gt;&lt;/i&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;(&lt;i&gt;a&lt;/i&gt;) x&lt;/span&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;&amp;nbsp;&lt;/span&gt;&lt;i&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;f&lt;/span&gt;&lt;/i&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;(&lt;i&gt;b&lt;/i&gt;)&amp;lt;0 y localizamos el valor
inferior a&lt;/span&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt; y el valor superior b&lt;/span&gt;&lt;sub&gt;i&lt;/sub&gt;&lt;span style=&quot;line-height: 115%;&quot;&gt;&amp;nbsp; del intervalo que encierra la raíz &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;line-height: 115%;&quot;&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Paso &amp;nbsp;2: Realizar
una aproximación de la raíz mediante la relación:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;line-height: 17px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Paso 3: Evaluar para determinar en que
subintervalo esta la raíz.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&amp;nbsp;Si
&amp;nbsp;f(a&lt;sub&gt;i&lt;/sub&gt;).f(b&lt;sub&gt;i&lt;/sub&gt;)&amp;lt;0 &amp;nbsp;Entonces la raíz se encuentra dentro del
subintervalo inferior&amp;nbsp; o izquierdo por lo
tanto se hace &amp;nbsp;a&lt;sub&gt;i+1&lt;/sub&gt;=x&lt;sub&gt;i&lt;/sub&gt;
; b&lt;sub&gt;i&lt;/sub&gt;=b&lt;sub&gt;i&lt;/sub&gt; &amp;nbsp;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;o:p&gt;&amp;nbsp;&lt;/o:p&gt;Si &amp;nbsp;f(a&lt;sub&gt;i&lt;/sub&gt;).f(b&lt;sub&gt;i&lt;/sub&gt;)&amp;gt; 0 &amp;nbsp;Entonces la raíz se encuentra dentro del
subintervalo superior derecho &amp;nbsp;por lo
tanto se hace &amp;nbsp;&amp;nbsp;a&lt;sub&gt;i+1&lt;/sub&gt;=a&lt;sub&gt;i&lt;/sub&gt;
; b&lt;sub&gt;i+1&lt;/sub&gt;=x&lt;sub&gt;i&lt;/sub&gt; &amp;nbsp;&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Si &amp;nbsp;f(a&lt;sub&gt;i&lt;/sub&gt;).f(b&lt;sub&gt;i&lt;/sub&gt;)=0 &amp;nbsp;La raíz es igual a x&lt;sub&gt;i&lt;/sub&gt; , se termina el
calculo&lt;/span&gt;&lt;/li&gt;
&lt;/ul&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Paso 4: &lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;line-height: 17px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;/span&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Entonces se deja de iterar cuando x&lt;sub&gt;i&lt;/sub&gt;
=r, con la cantidad de cifras significativas exactas o de cifras decimales
exactas según como se pida caso contrario ir al paso 2.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Ejemplo &lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;Sea la función donde xє[0,3]&lt;/span&gt;&lt;/div&gt;

en la cuarta iteración?&amp;nbsp;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;font: normal normal normal 7pt/normal &#39;Times New Roman&#39;; text-indent: -18pt;&quot;&gt;&lt;span style=&quot;font-size: small;&quot;&gt;&amp;nbsp; &lt;b&gt;&amp;nbsp;b)&lt;/b&gt;&amp;nbsp;&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;text-indent: -18pt;&quot;&gt;¿Cuántas cifras decimales tiene la solución

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;font-family: Arial, Helvetica, sans-serif;&quot;&gt;&lt;span style=&quot;text-indent: -18pt;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Solución &lt;/b&gt;&lt;o:p&gt;&lt;/o:p&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Primero buscamos el&amp;nbsp; intervalo donde podemos encontrar al menos

&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Definición de errores&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
Estos errores surgen al momento de realizar aproximaciones &amp;nbsp;al representar operaciones y cantidades
matemáticas&amp;nbsp; debido &amp;nbsp;a la imposibilidad de controlar la influencia
de todas las variables.&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Error absoluto&lt;/b&gt; (Ea):
&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #333333; font-family: Arial, sans-serif; font-size: 10pt; line-height: 115%;&quot;&gt;el error absoluto es la es la diferencia del
valor de la aproximado (medida) y el valor tomado como exacto, el resultado &amp;nbsp;puede ser negativo o positivo, según se la
medida es superior al valor real o inferior (la resta sale positiva o negativa)
&amp;nbsp;al cual se le sacara el valor absoluto. El
resultado tendrá las mismas unidades del valor exacto o aproximado.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #333333; font-family: Arial, sans-serif; font-size: 10pt; line-height: 115%;&quot;&gt;Sea&lt;/span&gt; p un valor
exacto o verdadero y p1 el valor aproximado&lt;br /&gt;

&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Error
relativo&lt;/b&gt; (Er):&lt;span style=&quot;background-attachment: initial; background-clip: initial; background-color: white; background-image: initial; background-origin: initial; color: #333333; font-family: Arial, sans-serif; font-size: 10pt; line-height: 115%;&quot;&gt; El error relativo resulta de la división entre el error absoluto y el
valor exacto. Este error no tiene unidades&lt;/span&gt;.&lt;o:p&gt;&lt;/o:p&gt;&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;

&lt;span style=&quot;font-family: Calibri, sans-serif;&quot;&gt;&lt;span style=&quot;font-size: 15px; line-height: 17px;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;/span&gt;

&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;b&gt;Cifras
significativas&lt;o:p&gt;&lt;/o:p&gt;&lt;/b&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;Son significativos todos los dígitos
distintos de cero.&lt;/li&gt;
&lt;/ul&gt;
&lt;o:p&gt;&lt;/o:p&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;color: red;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; 8723 &lt;/span&gt;&amp;nbsp;y&amp;nbsp; 0.0&lt;span style=&quot;color: red;&quot;&gt;4578&lt;/span&gt; tienen &amp;nbsp;cuatro cifras significativas&lt;o:p&gt;&lt;/o:p&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;Los ceros situados entre dos cifras
significativas son significativos.&lt;/li&gt;
&lt;/ul&gt;
&lt;o:p&gt;&lt;/o:p&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;span style=&quot;color: red;&quot;&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;105&lt;/span&gt;
&amp;nbsp;y&amp;nbsp;
0.0&lt;span style=&quot;color: red;&quot;&gt;205&lt;/span&gt; tienen &amp;nbsp;tres cifras significativas&lt;o:p&gt;&lt;/o:p&gt;&lt;/div&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&lt;/div&gt;
&lt;ul&gt;
&lt;li&gt;Los ceros a la izquierda de la primera
cifra significativa no lo son.&lt;/li&gt;
&lt;/ul&gt;
&lt;o:p&gt;&lt;/o:p&gt;&lt;br /&gt;
&lt;div class=&quot;MsoNormal&quot;&gt;
&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;0,00&lt;span style=&quot;color: red;&quot;&gt;5&lt;/span&gt; &amp;nbsp;y&amp;nbsp; 0.06 tienen
una cifra significativa&lt;o:p&gt;&lt;/o:p&gt;&lt;br /&gt;
&lt;b&gt;ORDEN DE DESCOMPOSICIÓN&amp;nbsp;POLINÓMICA&lt;/b&gt;&lt;br /&gt;
El orden de una&amp;nbsp;descomposición&amp;nbsp;polinomica viene a ser el exponente&amp;nbsp;máximo&amp;nbsp;de una descomposición polinomica&lt;br /&gt;
&lt;br /&gt;
&lt;b&gt;CIFRAS SIGNIFICATIVAS EXACTAS&lt;/b&gt;&lt;br /&gt;
