R is the radius of the circle. Notice that in the standard form of the equation of a circle, you need the CENTER and the RADIUS SQUARED. Also notice that X minus H squared and Y minus K squared are perfect squares. What if the Equation Isn’t in Standard Form? If you have something like…. x^2 + 20x + y^2 +16y = -20Ellipse Equation. Using the semi-major axis a and semi-minor axis b, the standard form equation for an ellipse centered at origin (0, 0) is: x 2 a 2 + y 2 b 2 = 1. Where: a = distance from the center to the ellipse’s horizontal vertex. b = distance from the center to the ellipse’s vertical vertex. (x, y) = any point on the circumference.
