uTo graph using polar coordinates (
r =) [Sketch]-[GRPH]-[r=]
You can graph functions that can be expressed in the format
r = f ( θ ).
Example To graph r = 2 sin3 θ
Use the following View Window parameters.
Xmin = –3 Ymin = –2 T, θ min = 0
Xmax = 3 Ymax = 2 T, θ max = π
Xscale = 1 Yscale = 1 T, θ pitch = π÷36
1. In the set up screen, specify “r =” for Func Type.
2. Specify “Rad” as the angle unit and then press J.
3. Input the polar coordinate expression (r =).
