# Definite Integral of sin^4x from 0 to pi/4

In this tutorial we shall derive definite integral of trigonometric function from limits 0 to Pi/4.

The integration of the form

Using half angle formula from trigonometry , we have

Again using half angle formula from trigonometry , we have

First we evaluate this integration by using integral formula , then we using the basic rule of definite integral , we have
