if sin^2 (A)+sin(A)=1; then what is the value of cos^2(A)+sin^4(A)=?

Question

Arun · Answer

Dear student We have, sin A + sin 2 A = 1 ...(1) ⇒ sin A = 1 – sin 2 A ...(2) Now cos 2 A + cos 4 A = ( 1 – sin 2 A ) + {(1 – sin 2 A )} 2 = sin A + sin 2 A [from (2)] = 1 [from (1)] Regards Arun (askIITians forum expert)
