Hi all,(adsbygoogle = window.adsbygoogle || []).push({});

I want to convert a curve from polar coordinates function to a parametric function.

The function is:

[itex] r = 2 \cdot \cos( 4\cdot\theta )[/itex]

I want to convert this for ( x(t), Y(t) ).

Why do I want this? Because I saw that wxMaxima make plots of parametric functions, but I don't know how to plot polar functions.

Thank you.
