Best ResponseYou've already chosen the best response.1here is wright answer tanx = (sinx/cosx) cotx = (cosx/sinx) sinx cosx (tanx  cot x) = sinx cosx (sinx/cosx  cosx/sinx) Cross multiply the equation in the braket and make the in same denomenator. =sin x cos x ((sin^2x  cos^2x)/(cosx sinx)) = sin^2x  cos^2x Replace sin^2 by 1  cos^2x = 1  cos^2x  cos^2x = 1  2cos^2x
