Question
To test whether the graph of a polar equation may be symmetric with respect to the line $\theta=\frac{\pi}{2}$, replace $\theta$ by______.
Step 1
Symmetry with respect to the line \(\theta = \frac{\pi}{2}\) means that if a point \((r, \theta)\) is on the graph, then the point \((r, \pi - \theta)\) should also be on the graph. Show more…
