# How do you find the eccentricity, directrix, focus and classify the conic section #r=8/(4-1.6sintheta)#?

##### 1 Answer

**Eccentricity is** **directrix is** **focus is at pole** **and the conic is ellipse .**

#### Explanation:

distance of directrix from the focus at pole. (-) sign indicates

that the directrix is below the focus and parallel to the polar axis.

pole parallel to the polar axis. Rectangular conversion:

Eccentricity is
