I am just getting started with tensor algebra using Mathematica. I could use some help with a simple problem I am starting with at my website:
An acquaintance of mine showed me how to solve this problem using the "FeynCalc" add-on to Mathematica, and his solution is also at my website:
How can I solve this problem using Mathematica without any add-on like FeynCalc, just using Mathematica's built-in tensor software?
The problem I'm having with FeynCalc is that it seems to require me to be online to some extent, even after downloading the software, whereas I would like to just work offline. Please feel free to contact me by email too, email@example.com. Thanks.
