For the curve

x=3 \cos \theta, y=3 \sin \theta

0 \leq \theta \leq \pi,

the tangent is parallel to the

x

-axis, where

\theta=

View answer and explanation

Correct option: D

\frac{\pi}{2}

Option D (

\frac{\pi}{2}

) is correct because at this angle, the derivative

\frac{dy}{dx}

equals zero, indicating a tangent parallel to the x-axis.
