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 ...
By one of the trigonometric identities, sin2y + cos2y = 1. From this, cos y = √1-sin²y = √1-x².Substituting this in (1),dy/dx = 1/√1-x² (or)d (arcsin x) / dx = 1/√1-x²Thus, the derivative of arcsin x (or) sin-1x (or) inverse sin x is 1/√1-...

To integrate the inverse trigonometric functions, say to integrate sin-1x, write "times 1" after it. i.e., sin-1x × 1. Then assume sin-1x as the first function and 1 as the second function and finally apply theUV formula. We need to use thesubstitution method of integrationalso in...
Users must determine the given indefinite integral. For the given indefinite integral, you will use the integration substitution method and undo the substitution to obtain the desired result.Answer and Explanation: The given integral is {eq}I = \int \tan^7(x) \sec^2(x) dx...(1) {/eq}...
The alternative to the results in Table 6.2.4 is to remember (and apply) the trig identities embodied in Table 6.2.5, namely,cos2x=1+cos2x/2,sin2x=1−cos2x/2, andsin2x=2sinxcosx. Table 6.2.6 lists integration formulas for produc...
], and sin(y) = x 2 Note that this is only defined when x is in the interval [−1, 1]. The other inverse functions are similarly defined using the corresponding trig functions. Some Useful Identities Here are a few identities that you may find helpful. cos −1 (x) +cos...
