If tangent tto the curve `x=at^(2),y=2at` is perpendicular to X-axis, then its pointt of contact is

If the tangent to the curve x=a\ t^2,\ \ y=2a t is perpendicular to x-axis, then its point of contact is (a) (a ,\ a) (b) (0,\ a) (c) (0,\ 0) (d) (a ,\ 0)

If the tangent to the curve x=a\ t^2,\ \ y=2a t is perpendicular to x-axis, then its point of contact is (a ,\ a) (b) (0,\ a) (c) (0,\ 0) (d) (a ,\ 0)

If the tangent to the curve x = at^2 , y = 2at is perpendicular to x-axis then what is its point of contact ?

If the tangent to the curve y=f(x) is perpendicular to y -axis then

If the tangent to the curve y=f(x) is perpendicular to y -axis then

The tangent to (at^(2), 2at) is perpendicular to X - axis at
