You mean fixed for all real values of i?

#62I hate how often these sprawly things are called cheetsheets:

#63I think the author's page (Alex Spartalis) deserves to be mentioned: https://www.alexspartalis.com/cheat-sheet.html He has the same version (v2.10) there and mentions that, "The Web version does not include the distribution functions due to file size restrictions. Email me if you would like a copy of these." That explains why pages 213-330 are missing. Someone should offer to upload the full copy to keybase.pub (or s…
It'd be nice if there was a cheat sheet for Category Theory as well.
I thought that part could be found in the link you provided, but seems like the author hadn't (2013) included CT in this almanac.

#64Nice touch: 4.15 FERMAT’S LAST THEOREM: ... General case when n>2 was proved by Andrew Wiles (1994). The proof is too long to be written here. See: http://www.cs.berkeley.edu/~anindya/fermat.pdf

#65Awesome! It only serves to remind me I know practically nothing about Mathematics. "Good Primes" and "Happy Primes" .. who'd have thought it ...

#66More “Cheat Book” than “Cheat Sheet” :)
Looks like it could do with typesetting in LaTeX - I think the author started doing this here: http://mathscheats.weebly.com/ but never entirely completed it. Plenty there to chew on though.

#67Earlier quoted context omitted.
I actually can't tell if that was an intentional "margin" joke, or if the author is just bluntly stating a fact about Wiles' proof... EDIT: Nope, probably intentional. The author doesn't say something similar for any other proof based on a quick CTRL+F :)
Fermat wrote that in the margin of his book Arithmetica that a proof existed, but there wasn’t space in the margin to write it. It took Wiles 385 years to find a proof, and it won’t fit in a margin. https://en.m.wikipedia.org/wiki/Fermat%27s_Last_Theorem That’s the allure of the theorem; that a simple unknown proof may exist.
There's some speculation that fermat made the same mistake as lamé, who thought he had a proof. However lamé incorrectly assumed unique factorisation of a general number field, which was an easy mistake to make at the time.

I sent a message using the contact form. Thanks for mentioning this.

#69I got a B in probability because I didn't write a proof of the central limit theorem on the allowed cheat sheet for the final exam. So of course it's the first thing I looked for on this one. It's not there.
A B is like 80% or so, judging from A being the best iirc? I'm not familiar with alphanumeric grading systems.
