Note: This only works when \(x\) is measured in radians. We are now going to look at more complex trigonometric functions where we will use the general rule: \(\int {\cos (ax + b)dx = \frac{1}{a}} ...
Remember that integration is the inverse procedure to differentiation. So, if you can do trigonometric differentiation, you can do trig integration.
Abstract: The properties of the operational matrices of integration, P, and differentiation Q, are discussed for the case of Fourier trigonometric functions. In particular, a theorem that establishes ...
