The Circle and Ellipse Summary

The Circle and the Ellipse

Summary

the conic sections are formed when planes intersect cones.

this section studies the geometry of the circle and the ellipse.

the equations of these curves can be written in (x, y) form or as parametric equations, which involve a third variable, t is often used.

Key Skills

describe conic sections (circle and ellipse) and sketch their graphs:

  • transformation of an equation to standard form
  • translating of conic sections.

Vocabulary

parabola, ellipse, conic sections, cone, parametric equations
