Question

The parametric coordinates of any point on the parabola $y^2=x$ can be

• A. $({\sec }^2\theta ,\sec \theta )$
• B. $({\sin }^3\theta ,\sin \theta )$
• C. $({\cos }^3\theta ,\cos \theta )$
• D. none of these

Answer 1

The correct option is A $({\sec }^2\theta ,\sec \theta )$

Out of the four options only option (A) satisfies the equation of parabola, Hence Option (A) is the correct answer.
