Question :
Prove :
Solution :
LHS![=\sf\frac{\sin\theta}{\cot\theta+\cot\theta} =\sf\frac{\sin\theta}{\cot\theta+\cot\theta}](https://tex.z-dn.net/?f=%3D%5Csf%5Cfrac%7B%5Csin%5Ctheta%7D%7B%5Ccot%5Ctheta%2B%5Ccot%5Ctheta%7D)
RHS![=\sf2+\frac{\sin\theta}{\cot\theta-\cot\theta} =\sf2+\frac{\sin\theta}{\cot\theta-\cot\theta}](https://tex.z-dn.net/?f=%3D%5Csf2%2B%5Cfrac%7B%5Csin%5Ctheta%7D%7B%5Ccot%5Ctheta-%5Ccot%5Ctheta%7D)
LHS = RHS
⇒1-cosθ=2-(1+cosθ)
⇒(1-cosθ)+(1-cosθ)=2
⇒2=2
Hence ,Proved
