Transforming from polar to parametric functions

[Aikon]

Hi all,

I want to convert a curve from polar coordinates function to a parametric function.
The function is:
$r = 2 \cdot \cos( 4\cdot\theta )$

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.

I don't know anything about wxMaxima but I'm sure you wouldn't be happy with the parametric equations you would get. Why don't you learn how to do it in wxMaxima? Try looking here:

Hi Kurtz,
Thanks, I will read the article later, it appears to be whatI need.
It is because of people like you that I love this forum.

See you,
