Lesson: Polar Equation of a Conic

In this lesson, we will learn how to determine the type of a conic section (ellipse, parabola, or hyperbola) and write polar equations of conics given the eccentricity and some other characteristic.

Worksheet: 5 Questions

Q1:

A conic with focus at the pole has eccentricity and vertices at and . Write the equation of the conic in polar form.

Q2:

Identify the type of the conic.

Write the equation of the conic in polar form.

Q3:

Identify the type of the conic.

By deciding whether the directrix is in the form , , , or , where , select the form of the polar equation of the conic.

By writing one of the vertices in polar form, find the equation of the directrix.

Hence, write the equation of the conic.
