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 \(∫\cos^jx\sin x\,dx\).Odd Power of Sine or Cosine. To integrate an odd power of sine or cosine, we separate a single factor and convert the remaining even power. If the power of cosine is odd (n = 2k + 1), save one cosine .
Integrating Products of Sines and Cosines. This section looks at integrals involving the product(s) of sine and cosine functions having different linear arguments, e.g. ∫ sin (a x) sin (b x) d x, or ∫ sin 2 (a x) cos (c x) d x. Use is made of the following three basic sine and cosine product identities involving different arguments:
We show how to integrate a product of sines and cosines, when either there are an odd number of sines or an odd number of cosines
Let’s begin our study with products of sin x sin x and cos x. cos x. Integrating Products and Powers of sinx and cosx. A key idea behind the strategy used to integrate combinations of products and powers of sin x sin x and cos x cos x involves rewriting these expressions as sums and differences of integrals of the form ∫ sin j x cos x d x .
Well, let's just rewrite this part right over here, leveraging some trig identities. And if this is completely unfamiliar to you, I encourage you to review your trig identities on Khan . 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.
Integrating Products of Sin(x) and Cos(x) If you’re integrating a product of sine and cosine, you will need to use an identity to simplify the function before integrating. For instance, the integral of sin(x)cos(x) can be simplified to .
