Use the identities sec^2 (x) = tan^2 (x) 1 and csc^2 (x) = 1 cot^2 (x), both are derived from the pythagorean identity of 1 = sin^2 (x) cos^2 (x) by dividing through by either sin 2 or cos 2 2 View Entire Discussion (1 Comments) Abhishek K LH S = sec2x csc2x = 1 cos2x 1 sin2x = sin2x cos2x sin2x ⋅ cos2x = 1 cos2x ⋅ csc2x = sec2x ⋅ csc2x = RH S Answer link
