"Web1) Replacing ( r, θ) ( r, θ) with ( − r, − θ) ( − r, − θ) yields the same result. Thus, the graph is symmetric with respect to the line θ = π 2. θ = π 2. 2) Replacing θ θ with − θ − θ does not yield the same equation. Therefore, the graph fails the test and may or may not be symmetric with respect to the polar axis. " - How do you find the axis of symmetry a graph
