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 ...
= x csc-1x + ln |sec u + √(sec2u - 1)| + C (by trig identities) = x csc-1x + ln |x + √(x2 - 1)| + C Therefore, ∫ csc⁻¹x dx = x csc-1x + ln |x + √(x2 - 1)| + C Answer: x csc-1x + ln |x + √(x2 - 1)| + C. Example 2: Evaluate...

∫cos3(x)sin4(x)dx Question: Find the following trigonometric integrals. ∫cos3(x)sin4(x)dx Indefinite Integral: Indefinite integrals are operations that can be applied to any function or constant. The function to be integrated is called the "integrand". Integration is...
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 ...
The evaluation begins with application of trigon√ometric identities, rewriting the integrand to 1 + cos2 x − sin2 x and then to 2 cos2 x. For this, the user simply needs to select cos 2x and then sin2 x, and choose the desired rewrite targets. The resulting situation is similar ...
