Ex 7.3, 2 sin 3 cos 4 We know that 2 sin A cos B=sin + + sin sin A cos B= 1 2 sin + + sin Replace A by 3 & B by 4 sin 3 cos 4 = 1 2 sin 3 +4 + sin 3 4 sin 3 cos 4 = 1 2 sin 7 + sin sin 3 cos 4 = 1 2 sin 7 sin Now, sin 3 cos 4 = 1 2 sin 7 sin = 1 2 sin 7 sin Now, sin 3 cos 4 = 1 2 sin 7 sin = 1 2 cos 7 7 + cos + = + +
