Transforming from polar to parametric functions

Click For Summary
SUMMARY

The discussion focuses on converting a polar function, specifically r = 2 · cos(4·θ), into parametric equations (x(t), y(t)). Users express a desire to plot these parametric functions using wxMaxima, a tool they are unfamiliar with. A resource link to a guide on plotting polar functions in wxMaxima is provided, emphasizing the importance of understanding the conversion process for effective plotting.

PREREQUISITES
  • Understanding of polar coordinates and their mathematical representation.
  • Familiarity with parametric equations and their formulation.
  • Basic knowledge of wxMaxima software for plotting functions.
  • Ability to interpret mathematical functions and transformations.
NEXT STEPS
  • Learn how to convert polar coordinates to parametric equations.
  • Explore wxMaxima's capabilities for plotting parametric functions.
  • Study the provided guide on plotting polar functions in wxMaxima.
  • Investigate additional resources on mathematical transformations and plotting techniques.
USEFUL FOR

Mathematicians, educators, students, and anyone interested in plotting mathematical functions using wxMaxima or converting between polar and parametric forms.

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,
