Integral of 1/sin^2 (x) (substitution) 1:49. (Method 1) Integral of 1/ (1+cos^2 (x)) (substitution Explanation: ∫ 1 1 + cosx dx = ∫ 1 − cosx (1 + cosx)(1 − cosx) dx. = ∫ 1 − cosx 1 − cos2x dx. = ∫ 1 − cosx sin2x dx. = ∫ 1 sin2x dx − ∫ cosx sin2x dx. = ∫csc2xdx − ∫cotxcscxdx. = −cotx + cscx + C.

Integrate 1/cosx. To integrate 1/cosx, also written as ∫ 1/cosx dx, 1 divided by cosx, (cosx)^-1, we start by using standard trig identities to to change the form. We recall the standard trig identity for secx. Therefore the integral of secx is the same thing, or identical in other words. At this point, we can simply look up the integral of secx in
We recall the standard trig identity for secx. Therefore the integral of secx is the same thing, or identical in other words. There are several ways to integrate 1/cosx, or secx; just look on Google.
