Another month has come and gone, so it's time to look back and tally up the page views and rank my top 5 most popular posts of May! There are few surprises once again, as it seems like my most popular material is REALLY popular, and everything else is just trying to keep up. Maybe I should consider doing a "10th place to 5th place most popular posts" write up, and maybe we'd get some different

This post continues along in my series on calculus differentiation rules, this time talking about how to find the derivative of a difference of functions. I hope you read my last post, which applied to sums of functions, because it is nearly the same situation when you are subtracting. I'm not going to go into the same level as detail as I did there, so I highly recommend you go back and give

Welcome back to my introductory calculus series on differentiation formulas.  For those who are playing along at home, I have explained several rules so far and am going to add another one today.  If you've missed those posts, then I highly encourage you to go back and take a look at them to familiarize yourself with these basic concepts.  (So far: here, here, and here.  Or

I know this may be a little late in the day, but I just realized that today's date is actually a Fibonacci sequence!  That's right, today's date is May 8, 2013, or written another way, 5/8/13! For those who don't know, the famous Fibonacci sequence is starts off with the numbers 0, 1, and then continues by adding numbers that are equal to the sum of its preceding two numbers.  So, the

In this post I'm going to explain another one of the differentiation rules for working with derivatives.  This time, I will show you how to find the derivative of a constant times a function. In case you have missed them, I am creating a series of posts that explain some basic concepts in differential calculus.  So far, in my first lesson I explained how to find the derivative of a

It's that time of month again - time for a recap of my top 5 most popular posts of April!  Once again, the top 5 are dominated by several of the usual favourites.  However, spot number 5 is a newcomer!  I'm happy to see that I have several pieces of content that are so routinely visited, but I also am very pleased to see new posts crack the top 5 as well from time to time.  If

Welcome to my second post of my series on differentiation formulas.  So far in my recent posts, I have explored in depth all about the concept of derivatives and using differentiation to find them, and then I started this current series with an easy theorem to remember for finding the derivative of a constant function.  This follow-up post will now explain to you probably one of the

For those of you just tuning in, my last post was a mega-post about derivatives and an introduction to differential calculus.  If you need some help getting started with understanding how to find derivatives, I highly recommend giving that a read.  One impression you may have of this concept is that it requires a lot of work - lots of lengthy formulas and limit calculations.  While

One of the main concepts studied in the field of differential calculus is based on the notion of change - specifically, how one quantity changes compared to another.  Perhaps a more succinct version of this physical definition would be "rate of change."  Alternately, a geometric definition could simply be the slope of a curve at a particular point.  The underlying key to this

I think I'm starting to see a trend with my posts! The top 5 most popular posts of March are a slightly shuffled variation of my top posts from February (you can take a look at those results here: http://sk19math.blogspot.com/2013/03/popular-posts-february-2013.html). There was a chance that one of those 5 might have dipped and allowed a new star post to rise, but alas, this was not the

A while ago, I posted a very popular post that explained how to calculate the midpoint of a line. A lot of people have viewed that page, and so I thought that this somewhat related story might also be equally as interesting for my viewers. Guillermo, over at "Proofs from the Book," has recently posted an interesting discussion about the Midsegment Theorem, which deals with the line that connects

Happy Pi Day 2013 everyone! To most of my regular followers, they know exactly what I'm talking about. To many others though, they may think I'm crazy or talking about some special dessert day and wonder if the pie comes with ice cream or whipped cream. Well, I guess if you're really into it, you could celebrate Pi Day with pie. Why not, right? Pi Day, of course, comes once a year - on March 14

When working with functions and their graphs, one of the most common types of problems that you will encounter will be to identify their domain and range.  This isn't necessarily a difficult problem to solve, once you know what domains and ranges actually are!  After all, these terms sound like they belong in geography or cartography, or a National Geographic magazine!  However,

Another month has come and gone, so in trying to maintain my new year's resolution, here is my monthly summary of my top 5 most popular posts of February 2013.  This is tabulated simply from the number of visitors each page on my blog receives.  I have recently started a Facebook page for my site as well, so eventually I would like to have these "best of" posts reflect the most shared

When you are graphing straight lines, one of the most common formats for describing the equation of the line is called "point slope form."  In this representation, the equation identifies one ordered pair that is on the line, and the slope.  If you were given only those pieces of information, you would have all that you would need to construct the line.  Continue reading to learn

Quick!  How many prime numbers can you recite, starting at 2 (1 is not prime!)?  Let's see... 2, 3, 5, 7, 11, 13, 17, 19, 23... the further you go, the more you have to think about it, right?  What you have to consider is whether each number you evaluate is only divisible by itself and 1, or if it can be divided by other numbers.  If it's only 1 and itself, you've found a

In one of my recently published posts here on my site, I discussed some options available for people looking to find free online courses with certificates.  Massive open online courses (MOOCs) have had an increasing role in education discussions over the last couple of years, and world-class institutions such as Harvard and Stanford now offer their own versions of distance learning degrees.

There is a bunch of videos going around lately that seem to be very popular, which demonstrate a style of Japanese multiplication.  It is quite visual, and I would argue that more complicated products could require even more work than traditional (at least, what I consider traditional) methods.  In any case, it is a very interesting process that you could use to impress your friends and
