Prove One Side Challenge

CBSE Class 10 · Solve it one decision at a time. A wrong pick earns a nudge, never the answer.

Step 1 of 3

The problem

Prove that 1−cos⁡2θsin⁡θ=sin⁡θ\dfrac{1 - \cos^2\theta}{\sin\theta} = \sin\theta, where sin⁡θ≠0\sin\theta \neq 0.
1−cos⁡2θsin⁡θ\dfrac{1 - \cos^2\theta}{\sin\theta}
→
?
sin⁡2θ+cos⁡2θ=1\sin^2\theta + \cos^2\theta = 1
