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

**Math- Conics**

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?

**Math/Conics**

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)
*Thursday, February 23, 2012 at 3:30pm by Reiny*

**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|.
