Question

Which comparison best explains the most direct technique for the expression below?

$$4\sin^{2}(x)$$

Accepted Answer

$$	ext{Use the power-reduction identity before applying basic antiderivative rules.}$$

Answer

$$	ext{Use parts because }\sin^{2}(x)	ext{ is a product that simplifies no further.}$$

Answer

$$	ext{Use the power rule on }\sin^{2}(x)	ext{ as though }\sin(x)	ext{ were }x.$$

Answer

$$	ext{Use substitution }u=\sin(x)	ext{ because }\cos(x)	ext{ is present as a factor.}$$
