Answer with explanation:
When point (x,y) in two dimensional plane is converted to polar plane,that is in terms of (r,α)
1. Origin (0,0)→Pole
2. x=0,y=0 becomes can be written as→ equation of polar axis,which is equal to 0.
the two curves drawn here has following line of symmetry
1. Symmetry along four lines of blade shaped curve,one along polar axis that is x=0,y=0 and two along,x=y and y=-x.
2. The curve which is in the shape of Cardioid has 1 line of symmetry that is , x=0.
The features which are present in the polar graph
Option:
A. Symmetry about the line
B. Symmetry about the polar axis = 0
