Graphing with SageMath (Sage) on an X/Y Axis for Beginners

Introductory tutorial on Cartesian graphing using SageMath (a/k/a Sage). Discussion of how to use SageMath's plot() to graph a mathematical function, customize the look of your graph (color, title, etc.) with different "options" in plot(), store your graph in a variable and use it later in your program, plot multiple lines on the same graph, and save your graph to your files as a PDF or other format. No prior knowledge of Python or SageMath is assumed. Timestamps are below.

This video uses SageMath 9.1. To download the current version of SageMath and to learn more, visit https://www.sagemath.org/.

The SageMath documentation can be found here: https://doc.sagemath.org/ To learn more about 2D plotting with SageMath in particular, visit https://doc.sagemath.org/html/en/refe.... Another excellent resource is the textbook Computational Mathematics with SageMath, available here: http://sagebook.gforge.inria.fr/engli....

In this video I make some references to Python, Matplotlib, and Sympy. No prior knowledge of these is necessary to follow along, but if you would like to learn more about each of these, visit https://www.python.org/, https://matplotlib.org/, https://www.sympy.org/en/index.html.
