Apply the appropriate power reduction identity to rewrite $\sin^4 \theta$ in terms of $\sin \theta$ and $\cos \theta$ (and both must only have the first power). In this case it is obviously not true. Multiply by the reciprocal of the fraction to divide by sin() cos() sin ( ) cos ( ). This problem has been solved! (Round your answer to four decimal places.) The Integral Calculator solves an indefinite integral of a function. Replace cosine with its reciprocal function. The problem asks to rewrite sin ( x) cos ( x) in the form of A sin ( x + C), using the reduction formula. You may already see why we paired them the way we did from the names alone. With so many formulas and identities its difficult to know what to use. We can then use the power reduction formula, $\sin^2\theta = \dfrac{1}{2}(1 - \cos \theta)$.
