To identify any symmetry and zeros of
Answer to Problem 89CR
The symmetry is at
Explanation of Solution
Given information:
The polar equation is
Calculation:
Replace
So, by the use of even trigonometric identity, it is concluded that the curve is symmetric with respect to
0 | |||||||
1 |
Now, the graph is represented to verify the obtained results,
Therefore, the graph is limacon with inner loop. Hence the obtained is verified from the graph as symmetry is at 4 that is
