Given that

Integrate the sum, terms by terms and factor out constants

For integrand

For integrand u = -2+x  and du = dx

For integrand

Then

Write

Integrate the sum terms by terms and factor out constants

For integrand  cos2s substitute p = 2s and dp = 2ds

The integral of cosp is sinp

The integral of 1 is s

The integral of

The integral of

Substitute back p = 2s

Substitute back

Substitute back u = -2+x

Take common 1/24
