1-cosx/1+cosx=(cotx-cscx)^2

1. (sinx/cscx)+(cosx/secx)=1 2. (1/sinxcosx)-(cosx/sinx)=tanx 3. (1/1+cos s)=csc^2 s-csc s cot...

Prove that cscx / cosx = tanx + cotx

prove identity cscx-(cosx)(cotx)=sinx

pROVE THAT (cotx - tan x)cosx=cosec1x-2sinx

cosx/secx+sinx/cscx=sec^2x-tan^2x

(cotx + cscx(1-cosx)= SIN x

y= cotX / cosX-4

cscx+1/cscx cosx = secx+tanx

if cosx = -0.7 and cscx > 0, the terminal side of angle x is located in quadrant ___.

If f(cosx) = cotx and 0 < x < 0.2, find a formula for f(2x).
