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

cosx/1-tanx + sinx/1-cotx = sinx =cosx

Is y equal to cotx, tanx, cosx, or sinx if its graph is periodic with a period of 2pi, an amplitude...

prove cosx+cotx/secx+tanx =cosxcotx

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

Prove: (cotx sinx)(secx-cosx)=sin^2(X)

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

if cotx+tanx=a and secx-cosx=b then prove that (a^2b)^0.6667 -(ab^2)^0.6667=1

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

y= cotX / cosX-4

show that sinx/(1-cotx)+cosx/(1-sinx)=sinx+cosx thanks
