# 77-80 Polar Equation of Conics A polar equation of a conic is given.(a) Find the eccentricity, and identify the conic.(b) Sketch the conic, and label the vertices. r = 2 3 + 2 sin θ

To determine

(a)

To find:

The eccentricity, and identify the conic.

Explanation

Given:

r=23+2sinθ

Approach:

A polar equation of the form r=ed1±ecosθ or r=ed1±esinθ represents a conic with one focus at the origin and with eccentricity e. The conic is

a parabola if e=1(1)

an ellipse if 0<e<1

To determine

(b)

To sketch:

The conic and label the vertices.
