[Maxima] cardioid

[Adam Majewski]

Hi

Thx for all answers.

1. I think that in polar form cardioid:
e1:exp(t*%i)/2-exp(2*t*%i)/4;

can't be drawn since polar plots have "center " in point 0 (
This cardioid really has radius equation:
r:  (1-cos(theta))/2;

but it has to be moved to the right 1/4 unit.
It can't be done in polar form

2. You say: "You're converting expression to polar form incorrectly."
Can you show me how to do it correctly ?

Regards

Adam
