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

Answer: (D)

$θ=n\pi,n ∈z$

Answer 2

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