Integrate sin^2(x) with respect to x

use trigonometric identities i.e. Cos(2x) = Cos 2 (x) - Sin 2 (x) (a) Cos 2 (x) + Sin 2 (x) = 1 (b) Therefore: Cos 2 (x) = 1 - Sin 2 (x) (c) Combining (a) and (c) we achieve Cos(2x) = 1 - 2 Sin 2 (x) Rearran...

Given that 2cos(x+50)°=sin(x+40)° show tan x° = tan 40°/3

The formulae for the sum the sine and cosine of two angles are: 2(cos x°cos 50°- sin x°sin 50°)= sin x°cos 40°+cos x°sin 40°cos 50°= sin 40°sin 50° = cos 40° Therefore, 2 cos x°sin 40°- 2 sin x°cos 40° = sin...
