If 1 + sin^2θ = 3sinθ cosθ , then prove that tanθ = 1 or 1/2 .

What does sine actually mean?

10t.. Sin^8 theta - cos^8 theta = (1 - 2 sin square theta cos square theta) (1- 2 cos square theta)

Prove that Sin8 theta - cos8 theta = (sin2 theta - cos2 theta)(1-2sin2 theta + cos2 theta)

(sinA + cosA)/(sinA-cosA)+(sinA - cosA)/(sinA+cosA)=2/(sin^2A-cos^2A)= 2/(2sin^2A-1)=2/(1-2cos^2A)
