Integral of sin^2(x) using the Half Angle Formula
In this video, I demonstrate how to integrate the function sin^2(3x) by using its half angle formula equivalent. That is... sin^2(x) = [ 1 - cos(2*x) ] / 2 This powerful trig identity turns this into a very simple problem because we are reducing it's power from 2 to 1. Note that if I try to find the anti-derivative using the method of ...
