"Using Mathematica, construct space-time diagrams for which the speed of $S’$ moving in the positive x-direction with respect to $S$ and at speed $V$ with respect to $S$ for:
(c) $V=0.8c$ (on separate sheets).
Include gridlines for the $S’$ coordinate systems in each case."
These space-time diagrams look like this:
Where the black coordinate axis is the $S$ plane and the blue coordiante axis the $S'$ plane.
We just started special relativity and this was assigned. I know how to plot functions using Mathematica and thats about it. I do not want anyone to explicitly write the coding for me. If someone could maybe just tell me what functions to use, I will try learning those on my own and see what I can do with them.
