Visuals for an explanation of gradient descent for a calculus class project

To get rid of a warning about Unsupported element type: <class 'svgelements.svgelements.Use'>, line 153 of mobject/svg/svg_mobject.py was changed to if isinstance(shape, (se.Group, se.Use)): . See 3b1b/manim#1904 for more details.

To run an animation and save it as an MP4:

source venv/bin/activate
manimgl ClassName.py ClassName -w --uhd --file_name out.mp4

Saving as a GIF creates files that are easily hundreds of MB, so MP4 is preferred.
