Chapter 10: Q 40. (page 683)

e=23; directrix is parallel to the polar axis 3units above the

pole.

Short Answer

Expert verified

The polar equation is

r=63+2sin(胃)

Step by step solution

01

Step 1. Given information 

e=23;

The directrix is parallel to the polar axis 3units above the

pole.

02

Step 2. Identify e and p

It is given that

e=23

And directrix is parallel to the polar axis 3units above the

pole.

So,p=3

03

Step 3. Set up the polar equation

It is given that focus is at the pole.

The directrix is parallel to the polar axis 3units above the pole.

So, we can apply standard polar equation formula

r=ep1+esin(胃)

Plug values e=23,p=3

r=23脳31+23sin(胃)r=2脳33(1+23sin(胃))r=63+2sin(胃)
