Integral of sin^2x | Calculus 1 Exercises

Описание: We evaluate the integral of sin^2(x) using a pair of trigonometric identities. The integral becomes very easy if we use the double angle identity for cos(2x) and the familiar Pythagorean identity. We'll find the integral of sin(x)^2 is x/2 - (1/4)sin(2) + C. #Calculus1
