integrating sine and cosine products*******A key idea behind the strategy used to integrate combinations of products and powers of sinx and cosx involves rewriting these expressions as sums and differences of integrals of the form ∫ sinjxcosxdx or ∫ cosjxsinxdx. After rewriting these integrals, we evaluate them using u -substitution. .

We generalize this integral and consider integrals of the form \(\int \sin^mx\cos^nx\ dx\), where \(m,n\) are nonnegative integers. Our strategy for evaluating these integrals is to use the identity \(\cos^2x+\sin^2x=1\) to convert high powers of one trigonometric function into the other, leaving a single sine or cosine term in the integrand. Example \(\PageIndex{2}\): Integrating powers of sine and cosine. Evaluate \(\int\sin^5x\cos^9x\ dx\). Solution. The powers of both the sine and cosine terms are odd, therefore we can apply the techniques of Key Idea 11 to either power. We choose to work with the power of the cosine term since the previous example used the sine term's power. In this section we look at how to integrate a variety of products of trigonometric functions. As a collection, these integrals are called trigonometric integrals.They are an important part of the integration technique called trigonometric substitution, which is featured in Section 2.3: Trigonometric Substitution.This technique .Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this siteSubsection 2.2.1 Products of Powers of Sine and Cosine. Functions consisting of powers of the sine and cosine can be integrated by using substitution and trigonometric identities. These can sometimes be tedious, but the technique is straightforward. When integration limits were from $0$ to $2\pi$ and the function was $\sin x \cdot \cos^2 x$ and also when the function was $\cos x \cdot \sin^2 x$,answer is $0$, so is there a standard formula when .

Integrating Products and Powers of sin x and cos x. A key idea behind the strategy used to integrate combinations of products and powers of \(\sin x\) and \(\cos x\) involves rewriting these expressions as sums and differences of integrals of the form \(∫\sin^jx\cos x\,dx\) or \(∫\cos^jx\sin x\,dx\).Case 2: Suppose our integration is of the form. \int \sin^m (x) \cos^n (x)dx, ∫ sinm(x)cosn(x)dx, where m m and n n belong to integers. In this case, we can solve it using u u -substitution: \cos (x) = t cos(x) = t and proceed. \sin (x) = t sin(x) = t and proceed. \cos (x)=t cos(x) = t otherwise.

Both exponents are even. For this case, we rely on the double-angle formula for cos. cos(2x) = 2cos2x 1 (1) = 1 2sin2x: (2) In fact, we will take these two forms and solve them for cos2xand sin x, respectively. This gives us the formulae cos2x = 1 + cos2x 2 (3) sin2x = 1 cos2x 2 (4) (5) Many of you will recognize these as the half-angle formula .

Express the following product as a sum containing only sine or cosine and no products: \(\sin(4\theta)\cos(2\theta)\). Solution. Write the formula for the product of sine and cosine. Then substitute the given values into the formula and simplify.
