Standard Form of the Equation of an Ellipse with Center (0,0)(0, 0)

The standard form of the equation of an ellipse centered at the origin, (0,0)(0, 0), is x2a2+y2b2=1\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1. In this form, the xx-intercepts are located at (a,0)(a, 0) and (a,0)(-a, 0), while the yy-intercepts are located at (0,b)(0, b) and (0,b)(0, -b). The orientation of the ellipse depends on the relationship between aa and bb: if a>ba > b, the major axis lies on the xx-axis (horizontal); if b>ab > a, the major axis lies on the yy-axis (vertical).
