Answer with explanation:
In a two-dimensional plane, when the point (x,y) is transformed into polar coordinates (r,α)
1. The origin (0,0) corresponds to the pole.
2. When x=0 and y=0, it translates to the equation of the polar axis, which equals 0.
The two curves featured here exhibit the following symmetries:
1. Symmetry across four lines of the blade-shaped curve, including one along the polar axis at x=0 and y=0, and two along x=y and y=-x.
2. The Cardioid shape possesses one line of symmetry, found at x=0.
Characteristics of the polar graph include:
Option:
A. Symmetry about the line
B. Symmetry about the polar axis = 0
