Sketch the graph of the given polar equation using symmetry, zeros, maximum r- values or any additional points.
Answer to Problem 100RE
Graph is shown below for the given polar equation.
Explanation of Solution
Given:
The polar equation is,
The polar equation is,
Symmetry:
Replace
With
Therefore,
Now Replace
With
Therefore,
Replace
With
Therefore,
Therefore, it is symmetric about the polar axis, pole and the line
Maximum value and zeros:
The maximum value of r is when
And the maximum value is 1
Now,
The graph of the equation is shown below.
