determine the following integrals: [(sin^2(2x)+cos^2(2x)(x^2 - 2cospie + 2/x^2) ] dx

Question

Note it is often necessary to simplify the integrand first

Answer 1

Just looking at the expression

(sin^2(2x)+cos^2(2x)(x^2 - 2cospie + 2/x^2)

There are 4 left-hand brackets and only three right-hand brackets.

There should be the same number of each.

Could you check if you have a right-hand bracket missing, or do you have an extra left-hand bracket that shouldn't be there.
