Week 2 Trigonometric integrations:
Hint to solve:
Expand the binomial:
you get 3 integrals :
Use the fact that to integrate each of the terms

Integration by Parts:
If you have a function that you want to integrate and it is a combination of 2 functions:
u and v , we are going to use a property of derivatives to obtain the formula for integr

I=
by using the substitution x= tan
Then this expression can be reduced to: this integral

We finally get the answer: I= that is I =
From our substitution we can
