# Evaluate the integral. ∫ 0 π / 4 1 + cos 2 θ cos 2 θ   d θ

To determine

To calculate: The value of integral function.

Explanation

Given information:

The integral function is 0π4(1+cos2θcos2θ)dθ (1)

Calculate the value of integral function as shown below:

Integrate Equation (1) with respect to θ and apply the upper and lower limits.

0π4(1+cos2θcos2θ)dθ=0π4(1cos2θ+cos2θ
