Sin((n+1)x)×sin((n+2)x)+cos((n+1)x)×cos((n+2)x) |
|
Answer» sin [(n+1)x)] × sin [(n+2)x] + cos [(n+1)x]×cos[(n+2)x]=?SOLUTION------sin (nx+x) × sin (nx+2x) + cos (nx+x) × cos (nx+2x) = cos (nx+2x) × cos (nx+x) + sin (nx+2x) × sin (nx+x).We know that--- cosA × cosB + sinA × sinB = cos (A-B)So we put value of A is (nx+ 2x) and value of B is (nx+x).cos (A-B)= cos ( nx+2x -nx-x )= cos (2x-x)= cos x ( Ans.) Lhs. It is in the form of cos(x+y) Cos ((n-1)x-(n+2)x) Cos (x(n-1-n-2)) Cos(x(-1) Cos(-x) Cos x |
