We use substitution: If n is odd (that is if the power of cosine is odd) we can use substitution with u = sin x, du = cos xdx and convert the remaining factors of cosine using cos2 x = 1 ? sin2 x. This will work even if m = 0. Example. / sin5 x cos3 xdx. Annette Pilkington. Trigonometric Integrals

Trigonometric Integrals. In this section we use trigonometric identities to integrate certain combinations of trigo- nometric functions. We start with powers of sine and cosine. EXAMPLE 1 Evaluate . SOLUTION Simply substituting isn't helpful, since then . In order to integrate powers of cosine, we would need an extra factor.

This handout describes techniques of integration involving various combinations of trigonometric functions. It also describes a technique known as trigonometric
Integrals involving trigonometric functions are commonplace in engineering mathematics. This is especially true when modelling waves, and alternating current circuits. When the root-mean- square (rms) value of a waveform, or signal is to be calculated, you will often find this results in an integral of the form. ? sin2 tdt.
