This can be derived just like sin(x) was derived or more easily from the result of sin(x). Given: sin(x) = cos(x); Chain Rule. Solve: cos(x) = sin(x + PI/2) cos(x) = sin(x + PI/2) = sin(u) * (x + PI/2) (Set u = x + PI/2) = cos(u) * 1 = cos(x + PI/2) = -sin(x) Q.E.D. 1) 1.

The reciprocal sine function is cosecant: \frac{1}{\sin(x)}=\csc(x).

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 \(∫\cos^jx\sin x\,dx\). d (sin x) = cos x dx.
