Wow it's that easy. I was making it harder that it is. I think thats how you set it up, but wouldn't 32^2 be 1024

What do you do when you have a rotated conic, and you are trying to find the angle and it comes to be tan= undefined. Do I pick 90, or 270?

correction: using x^2/a^2 = y^2/b^2 = -1 should say using x^2/a^2 - y^2/b^2 = -1

centre is clearly (0,0) a^=9 , b^2=16 so the major axis is along the y-axis vertices: (0,4), (0,-4), (3,0), and (-3,0) focal points: c^2 + 3^2 = 4^2 c = ±√7 foci: (0,√7), and (0,-√7)

conics
slope of PO= y/x slope of PN = y/(x-12) For segments to be perpendicular their slopes must be negative recipricols Thus, -x/y=y/(x-12) y^2+x(x-12)=0 Distribute the x, complete the square, and then you'll have the equation of a circle.

Given David's excellent answer to your previous post, it should be clear that A and B are endpoints of a diameter of a circle. The circle is centered at the midpoint of AB with diameter |AB|.
