Problem 73E

Equations of circles Use the results of Exercise to describe and graph the following circles.

r2 − 2r(−cos θ + 2 sin θ) = 4

Step-by-Step Solution:

Solution 73E

Step 1:

In this problem;

We have to describe and graph of the  circle

We know that the polar equation represents  a circle of radius ‘R’ centered at ( a, b).

Consider ,

By , using the above result  represents a circle.

So , here  a =  -1, b = 2 , and  = 4

= 4

= 4

= 4

+ 4 = 9

= 3.

Therefore , represents a circle of radius ‘’ centered at ( -1, 2).
