f(x)=\cos x

then

\int\left(2(f(x))^2-1\right)\left(4(f(x))^3-3\right.

f(x)) \mathrm{d} x

is equal to

View answer and explanation

Correct option: A

\frac{1}{10} \sin 5 x+\frac{1}{2} \sin x+C

The correct answer is A because using trigonometric identities to simplify the integrand and then integrating yields the result.
