Trig Integrals without Trig Identities
Sprows, David J.
PRIMUS, v18 n2 p158-160 Mar 2008
The standard approach to finding antiderivatives of trigonometric expressions such as sin(ax) cos(bx) is to make use of certain trigonometric identities. The disadvantage of this technique is that it gives no insight into the problem, but relies on students using a memorized formula. This note considers a technique for finding antiderivatives of such trigonometric expressions that is based on the product rule for derivatives and the inverse relation between the derivative and the indefinite integral.
