### Jun 21, 2010 · (1-sinx) / cosx + cosx / (1-sinx) cross multiply [(1-sinx) ^ 2 + (cosx) ^ 2] / [cosx(1-sinx)] [1 - 2sinx + sinx ^ 2 + cosx ^ 2] / [cosx(1-sinx)] using the identity sinx ^ 2 + cosx ^ 2 = 1 we get [2 - 2sinx] / [cosx(1-sinx)] factor out the 2 [2(1-sinx)] / [cosx(1-sinx)] the (1-sinx) cancle. 2 / cosx. using the identity 1 / cosx = sec x. 2secx. So

Mar 16, 2017 · I can't seem to prove these trig identities and would really appreciate help: 1. cosx + 1/sin^3x = cscx/1 - cosx I changed the 1: cosx/sin^3x + sin^3x/sin^3x = cscx/1-cosx Simplified: cosx + sin^3x/sin^3x = cscx/1-cosx I don't . math. If e^y=tanx, 0 . integral Nov 26, 2006 · The two identities that are important for this equation are: (sin x)/(cos x) = tan x (sin x)^2 + (cos x)^2 = 1. I found it easiest to work on the right side of the equation, and figure it in terms of sin x. 1 + sinx = sin^2(x/2) +cos^2((x/2) + 2sin(x/2)*cos(x/2) ={sin(x/2) +cos(x/2)}^2 Similarly, 1-sinx = sin^2(x/2)+cos^2(x/2) - 2sin(x/2)*cos(x/2) ={sin(x/2)- cos(x/2)}^2 sinx sinxcos x sin x−= 23.

sinx b.

The sum would be cos2x+ 1− 2sinx +sin2x (1− sinx)cosx. = 2− 2sinx (1 −sinx)cosx. = 2 cosx. =2secx.

In this case, it's the left hand side (LHS). LHS = (cosx) / (1 + sinx) + (1 + sinx) Feb 17, 2008 · Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything. May 22, 2008 · combine the fractions. cos^2 x + (1-sin x)^2 / [cos x* (1-sin x)]=2sec x. simplify a little.

In this case, it's the left hand side (LHS). LHS = (cosx) / (1 + sinx) + (1 + sinx) Feb 17, 2008 · Question : cosx/1-sinx=1+sinx/cosx Let's work with the left hand side We're going to times cosx/1-sinx by 1+sinx/1+sinx, you can do this because 1+sinx/1+sinx is equal to 1, so you aren't really changing anything.
