TRIGONOMETRIC INTEGRALS the guidelines are not as clear-cut. We may need to use identities, integration by parts, and occasionally a little ingenuity.

Find TRIGONOMETRIC INTEGRALS the guidelines are not as clear-cut. We may need to use identities, integration by parts, and occasionally a little ingenuity. Example If an even power of tangent appears with an odd power of secant, it is helpful to express the integrand completely in terms of sec x Find Powers of sec x may require integration by parts, as shown in the following example.
