Question

If the parametric equation of curve is given by x = cosθ + log tan \(\frac{θ}{2}\) and y = sinθ, then the points for which \(\frac{dy}{dx}=0\) are given by

• A. \(θ=\frac{n\pi}{2},n ∈z\)
• B. \(θ=(2n+1)\frac{\pi}{2},n ∈z\)
• C. \(θ=(2n+1)\pi,n ∈z\)
• D. \(θ=n\pi,n ∈z\)

Answer 1

The Correct Option is D

The correct answer is (D) : \(θ=n\pi,n ∈z\).
