So I finally decided to buy `Mathematica 11`

at the student price through my university. When it comes to indefinite integrals, I’ve found `Mathematica`

to be more reliable than my favorite opensource CAD, `SymPy`

. (Yeah, there are others I haven’t tried sufficiently, yet…)

So, anyway… I got it, so now I gotta install it on my archlinux laptop, right?

Thankfully, there is an AUR package for Mathematia. I use `yaourt`

as a frontend to AUR. Since Mathematica is a large package, yaourt needs to be instructed to use a temporary directory that is on disk, not tmpfs mounted. I do this:

`$ TMPDIR=/var/tmp yaourt -S mathematica`

Then, edit the PKGBUILD file so as not to install all the documentation, since I use the web most of the time anyway. Sure, I may sometimes get in trouble without internet. Whatever.

While editing the PKGBUILD, it is also important to copy over the Mathematica install file. Since I use VIM, I do `:shell`

, and create a symlink

`$ ln -s /path/to/Mathematica_11.1.1_Install.sh`

After exiting the install, just need to say yes a few times, and let the scripts do their work.
