Homework Statement
Given the points P0 = (0,a), P1 = (b,0), P2 = (0,0), write the parametric equation of a circle that intersects the 3 points.
Assume that b > a and both are positive.
Homework Equations
X = h + rcos(t)
Y = k + rsin (t)
r = √((x-h)2 + (y-k)2
Cos (t) = (x-h)/r
Sin (t) = (y-k) / r
The Attempt at a Solution
I'm having a really hard time visualizing parametric equations. I drew the circle and know that the challenge is finding the center, but I don't know how to express it. the circle is shifted right and up. I don't know how to express the coordinates of the center in terms of P0 and P1 as well as so it would intersect both these two points as well as (0,0).
