Answer» Let theta = x Given,cos x + sin x = √2cos x Then, (√2 -1)cos x = sin x on multiplying both sides by (√2+1) , we get(√2+1)(√2-1)cos x = (√2+ 1) sin x⇒ cos x = √2sin x + sin x⇒ cos x - sin x = √2sin x thank

Answer»

Let theta = x

Given,cos x + sin x = √2cos x Then, (√2 -1)cos x = sin x

on multiplying both sides by (√2+1) , we get(√2+1)(√2-1)cos x = (√2+ 1) sin x⇒ cos x = √2sin x + sin x⇒ cos x - sin x = √2sin x
