If you are surrounded by dumb ass retarded design software dev cs niggers it doesnt mean that all cs faggots are gay with math. CS requires a lot of heavy math on higher levels and im pretty sure that every cs tranny gorilla at least know calculus and linear algebra

Typically you forget what you're not using on a regular basis. Most of the higher math requirements are just a clusterfuck of abstract bullshit that isn't relevant in the real world. CS majors are too busy earning money and getting head from your mom to be concerned with higher mathematics.

0/0 is not meaningless, it's just that it's not unique. Any number satisfies 0*a = 0, therefore 0/0 is not a distinct element in a ring.

I already did. Given a ring $R$ , for any $a \in R$ $a*0 = 0$ and therefore (and this is an abuse of notation) $0/0 = a$ .

0/0 is meaningless because you're asserting that you can divide by zero. You can never divide by zero, it has no multiplicative inverse. I don't care what the numerator is.

Rings? Uniqueness? Come on, man.

Understood now, thank you. I have literally never heard of algebraic rings.

I have worked with Hilbert space though.

It's not that hard - they're just relatively few among everyone who does CS

You'll find all sorts of mathematical backgrounds in upper div and graduate CS - schools just suppress this in their advertising statements to attract codemonkeys who just want to take the development oriented courses that don't teach them anything. They *should* push them out, but also it's free money. Meanwhile, only the good students will care about pic related, which is from a second semester on algorithms focused on asymptotics of recurrences using some complex analysis

Do you know what a group is? A ring is just an algebraic structure (R, +, *) where (R, +) is an abelian group, * is associative and + is distributive over */

Why the fuck do characteristic equations work. Seems like magic that solving an associated polynomial gives a relationships between differentials of a function

>Why the fuck do characteristic equations work.
if you know how to differentiate exponentials it should be kind of obvious
each derivative adds a power to the constant, factor out the exponential and ignore it so know we just have a polynomial in the constants

0/0 just means the there is a hole in the function rather than 1/0 which would mean theres an asymptote. A hole is undefined but If you're approaching it with a limit you can can assume the hole is whatever the functions value would be.

I studied cs first. Started programming for more complex problems, released my basic linear algebra, discrete math and basic calc wasn't enough anymore. Self study would simply take too long and I wouldn't have a degree to show for my hard work.
Now back studying math and not regretting it.
My prior knowledge is really helping. Programming general solutions to a topic rather than only solving it on paper is really useful. I'm the only one that uses my own functions for my math study.

I don't need mathematics to succeed, however, I hate feeling like I have a chip on my shoulder because I didn't do cs at an elite university where they do it properly.

wat
introductory integrals and series convergence make sense, and you see them mundanely in generating functions and upper bounds. It is Turing Degrees and logic that kills the computer science student, but to be fair, this slays most students anyway ;^).

unless you have passion for pure math, cs is just more fun.
For example even if you come up with some new equation or proof, it is all theoretical work, at best you will get some other equation or a new number, with a computer and programming tools those equations can be used to build tools and can do all sort of cool things

lmao you don't know anything about research in either theory CS or math if all math comes down to you is "a new equation or number," and especially so if you don't know that there's a massive intersection between theoretical computer science results and math results.
