Pick GeoGebra if

You want students to build the construction themselves and see every formula.
Fourier series is one topic in a course that already lives in GeoGebra.
You need algebra, geometry or calculus tools alongside it.

Pick PathAnimator if

You want to show Fourier series working on any shape in seconds, including one a student draws.
You want a projector-ready classroom mode, stepping through one circle at a time.
You want a video or GIF of the result for slides, or a link students can open on their phones.

Questions

Can GeoGebra draw Fourier series with circles?

Yes, with some work: you build the circles from sequences and sliders, or use a construction someone has shared. PathAnimator computes them from any drawing, SVG, photo or text automatically.

Which is better for teaching Fourier series?

Use both. PathAnimator's explainer and classroom mode show the idea fast and let students try their own shapes; GeoGebra is the place for the class to build the maths step by step.

Does PathAnimator work without internet in class?

Yes. Open it once and add it to your home screen or desktop; the editor, the explainer and classroom mode then open without a connection.
