WebThe formula for tan 2x, in terms of sine and cosine functions is: Tan 2x = Sin 2x / Cos 2x Tan 2x = (2 sin x cos x) / (cos2 x – sin2 x) Now, substitute the known values in the formula, we get Tan 2x = [2 (5/12) (3/12)] / [ (9/144) – (25/144)] Tan 2x = (30/144)/ (-16/144) Tan 2x = -30/16, which on simplification, we get Tan 2x = -15/8.
