If the tangent at the point 
on the curve 
meets the curve again at
The given curve is ay2 = x3
The point of tangency is (at2, at3)
Let the point that tangent intersects again be (as2, as3)
We can find the slope of tangent by differentiating the given curve w.r.t x
Now, we will use two point form to solve the question.
If (x1, y1) and (x2, y2) be two points on the line then the slope is
For this question, it will be
We will solve it further and find the value.
(s - t) = 0
s = t
It means the same point of tangency. We want to find different point.
(2s + t) = 0
s =
So, the point will be
This is the required answer.

The curves 
and 
intersect orthogonally, then
The curves are as follows:
ax2 + by2 = 1 ...(1)
Ax2 + By2 = 1 ...(2)
We will take the derivative of equation (1) w.r.t x.
2ax + 2by
=0
2by= -2ax
This is this slope of first curve. We will call it slope1.
In the same way we will take the derivative of equation (2) w.r.t x
2Ax + 2By = 1
We will call it slope2.
The two curves are orthogonal. So, the product of their slope is -1.
Slope1 × Slope2 = -1
We will substitute (3) in (1)
We will substitute (4) in (2)
Divide (5) by (6)
This is the required answer.
