oh! thanks for pointing out my mistake , I've got the answer already :D thanks

Homework Statement (tanx - cosecx)2 - (cotx - secx)2 = 2(cosecx - secx)Homework Equations tanx = sinx/cosx cotx = 1/tanx = cosx/sinx cosecx = 1/sinx secx = 1/cosx The Attempt at a Solution LHS = (tanx-cosecx)(tanx-cosecx) - (cotx-secx)(cotx-secx) = tan2x - tanxcosecx - tanxcosecx +...
