(1-sinx)={cos(x/2)-sin(x/2)}^2 (1+cosx)=2×{cos(x/2)}^2; Hence,the given integral assumes the form [e^x×{1-tan(x/2)}^2]÷2; Put (1-tan(x/2))=z,thus,{sec(x/2)^2}/2dx=-dz; Therefore,[1+{tan(x/2)}^2]dx=-2×[e^{2arctan(1-z)}]dz, i.e,dx=-2dz/[1+{(1-z)^2}]×[e^{2arctan(1-z)}] =-2dz/(z^2–2z+2)×[e^{2arctan(1-z)}] 1. Proofs For each of these, we simply use the Fundamental of Calculus, because we know their corresponding derivatives. cos(x) = sin(x), cos(x) dx = sin(x) + c-sin(x) = cos(x), sin(x) dx = -cos(x) + c sec ^2 (x) = tan(x), sec ^2 (x) dx = tan(x) + c 2009-02-09 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.

2015-04-17 · Apr 17, 2015. First just do simple math : ∫ 1 − cos(x) 1 + cos(x) dx = −1 − cos(x) +2 1 +cos(x) dx. Now we can factorize the numerator : ⇒ ∫ −(1 + cos(x)) +2 1 +cos(x) dx. ⇒ ∫ −(1 + cos(x)) 1 +cos(x) dx + 2∫ 1 1 +cos(x) dx. ⇒ ∫ −1dx + 2∫ 1 1 +cos(x) dx.
