Question 1086893
Find the equation of the circle which passes through the points (-3,-4),(2,1), and (-6,5).
------------
I have an Excel sheet that does these:
----
<pre>
| x    y  x^2+y^2  1|
|-3   -4    25     1|
| 2    1     5     1| = 0
|-6    5    61     1|

</pre>

I enter the 3 points and get an equation for the circle.
Same for a parabola or hyperbola.
