WebExample 2: Using the values of angles from the trigonometric table, solve the expression: 2 sin 67.5º cos 22.5º. Solution: We can rewrite the given expression as, 2 sin 67.5º cos 22.5º = 2 sin ½ (135)º cos ½ (45)º. Assuming A + B = 135º, A - B = 45º and solving for A and B, we get, A = 90º and B = 45º.. ⇒ 2 sin ½ (135)º cos ½ (45)º = 2 sin ½ (90º + 45º) cos ½ … Web\(\implies\) sin 2A = 2 sin A cos A. We can also write above relation in terms of angle A/2, just replace A by A/2, we get. sin A = \(2 sin ({A\over 2}) cos ({A\over 2})\) (ii) Sin 2A …
