![Check Mark](/static/check-mark.png)
Answer to Problem 8CT
Solution:
The polar equation
Explanation of Solution
Given information:
The polar equation,
Explanation:
Use the test of symmetry with respect to polar axis, pole and line
Polar axis: Replace
Using
The resulting equation is same as original, so the graph is symmetric withrespect to polar axis.
The line
Since the resulting equation is not same as original, the graph may or may not be symmetrical about the line
The pole: Replace
The resulting equation is same as original, so the graph is symmetric with respect to pole.
Since the graph is symmetric about pole and polar axis, check the symmetry the line
The resulting equation is same as original, so the graph is symmetric with respect to line
Therefore the polar equation
