Two trigonometric identities are given by: (a) tan 3x = 3tanx tan3x/1 3tan2x (b) cos
Question:
(a) tan 3x = 3tanx – tan3x/1 – 3tan2x
(b) cos 4x = 8(cos4x - cos2x) + 1
For each part, verify that the identity is correct by calculating the values of the left and right sides of the equation, substituting x = 24o.
