Question

Prove that:
(a) sin^2(45°- 0) + sin^2(45°+ 0) = 1​

Answer 1

Sin^2(45)+cos^2(45)=1

It is by sin 90-ø=cosø

and sin^2ø+cos^2ø=1

mark me as brainliest my answer is correct

Answer 2

Step-by-step explanation:

(a) sin^2(45°-0) + sin^2(45°+0)

sin^2(45°)+ sin^2(45°)

(1/√2)^2 + (1/√2)^2 (sin45°=1/√2)

1/2+1/2

1

hence RHS=LHS
