Web18 apr. 2024 · 2. Please consider the following problem and my answer to it: Problem: Simplify the following expression: cos 2 x − sin 2 x sin 2 x. Answer: cos 2 x − sin 2 x sin 2 x = cos 2 x − sin 2 x 2 sin x cos x. cos 2 x − sin 2 x sin 2 x = cos x 2 sin x − sin x 2 cos x. The result is not much simpler than what I started with.
Websin2x = 2 sin x cos x Multiply and divide the above equation by cos x. Then sin2x = (2 sin x cos 2 x)/ (cos x) = 2 (sin x/cosx ) × (cos 2 x) We know that sin x/cos x = tan x and cos x = 1/ (sec x). So sin2x = 2 tan x × (1/sec 2 x) Using one of the Pythagorean trigonometric identities, sec 2 x = 1 + tan 2 x.
