2011-01-25T08:28:00.000-08:00

3 exercises on the integration to sum decomposition.

Exercises I

Adding and subtracting 1 to the numerator of the integrated function we get :

Exercises II

Calculate the indefinite integral

Reminding the definition of the tangent function, we get :

For sum decomposition we get :

Exercises III

Calculate the indefinite integral

Reminding the formula for duplication

which implies that

We get :

In the last step has been taken that D(sen2x) = 2cos2x.
