I have an ellipsoid with center (000). There is a point A inside the ellipsoid with known coordinates(1,2,3) I draw a line from center to point A and extend it to cut the ellipsoid on on point p(x,y,z).

## Homework Equations

I want to find the coordinates of point P(x,y,z)

## The Attempt at a Solution

The equation of ellipsoid for p is x^2/a^2+y^2/b^2+z^2/c^2=1

i have the values of a,b and c

i want to know if the ellipsoid equation is applicable to coordinates of A and coordinates of P

and how can i create equation using the coordinates of p with the coordinates of A

by equation of line method as both the points lie on a straight line with one end on (000) as the third point.
