Best ResponseYou've already chosen the best response.1do you know the equation of a circle? Start with the equation of an ellipse: \[ \frac{(xh)^2}{a^2} + \frac{(yk)^2}{b^2 } = 1 \] make the denominators equal. OK, let b = a so we have \[ \frac{(xh)^2}{a^2} + \frac{(yk)^2}{a^2 } = 1 \] or \[ \frac{(xh)^2+(yk)^2}{a^2} =1 \] if you multiply both sides by a^2 you get \[ (xh)^2+(yk)^2 = a^2 \]
