Did you know that the orbit of comets in space is an example of Real World Ellipses? In Conic Sections - Circles and Ellipses, you'll learn about the algebraic and geometric characteristics of two of the conic sections. With an Introduction to Circles, you will explore how Equations of a Circle are used in Calculating the Radius of a Circle and Calculating the Center of a Circle. We'll also learn about The Ellispe and their elements, such as the Foci and Major and Minor Axes. You will see how Coverting the Equation of an Ellipse to Center Format will help in Graphing an Ellipse.
