Given information
We are given that 
is any point on the parabola 
, except for the origin.
Step-by-step explanation
Step 1.
Let be any point on the parabola , except for the origin, and let 
be the point where the normal line intersects the parabola again.
be any point on the parabola , except for the origin, and let be the point where the normal line intersects the parabola again.Find the first derivative of with respect to 
with respect to 
At the point 
the slope of the tangent line is 
, then the slope of the normal line is 
. From the formula
the slope of the tangent line is , then the slope of the normal line is . From the formula
we get
Find the intersection of the point and the given parabola
and the given parabola
