A point on the curve x=3 , y=2 at which the tangent is perpendicular to X -axis is

Options

  1. A(3,0)
  2. B(0,3)
  3. C(0,-3)
  4. D(-3,3)

Correct answer

A. (3,0)

Step-by-step solution

Given curve is x=3 , y=2 is represent ellipse, x^2 9 + y^2 4 =1 and the tangent perpendicular to X -axis can be drawn at end points of the major axis means either at (3,0) or (-3,0) .
