A tangent to the parabola y 2 = 4ax makes an angle 45 0 with the x-axis. Then its point of contact is
Text Solution
Verified by ExpertsThe correct answer is:
A
We know that the slope of the tangent at ‘t’ to the parabola y 2 = 4ax is 1/t.
∴ ∴ 
= tan45 0 = 1 ⇒ ⇒ t = 1
∴ ∴ The required point is (at 2 , 2at) = (a, 2a)
