Question

please help me factor the question:

Prove: sin θ - sin θ•cos2 θ = sin3 θ. You must show all work.

Answer 1

\[Prove: \sin \theta - \sin \theta.\cos ^{2}\theta = \sin ^{3} \theta\]

\[= \sin \theta -(\sin \theta - \sin ^{3}\theta)\]
\[\sin \theta - \sin \theta + \sin ^ {3} \theta = \sin^{3} \theta\]
