How do I prove that (cosx -1) / cotx = sinx-tanx?
I always end with tanx (cosx-1)!
Am I not going far enough?

-
(cosx -1) / cotx = sinx-tanx
cosx/cotx -1/ cotx = sinx-tanx
cosx / cosx/sinx - 1 / cosx/sinx =
sin x - sinx/cosx =
sinx - tanx =
cosx/cotx -1/ cotx = sinx-tanx
cosx / cosx/sinx - 1 / cosx/sinx =
sin x - sinx/cosx =
sinx - tanx =
