Important Extra Questions on Trigonometric Identities for Proof

  1. If A, B, C are the angles of triangle ABC then prove that cosec2[(B + C)/2] – tan2(A/2) = 1.
  2. Prove the following: 2 (sin^6 A + cos^6 A) – 3 (sin^4 A + cos^4 A) + 1 = 0
  3. Prove that: (1 + cot A + tan A) (sin A – cos A) = sin A tan A – cot A cos A
