# Use the Table of Integrals on the Reference Pages to evaluate the integral. ∫ cos x   4 + sin 2 x   d x

To determine

To evaluate:

The integral cosx4+sin2xdx using the table of integrals.

Explanation

Calculation:

Let I=cosx4+sin2xdx………….(A)

Let u=sinx, so du=cosxdx.

Put these values in (A)

I=4+u2du=22+u2du.

Now, we use the formula,

u2+a2=uau2+a2+a22ln
