What is your credit card number and all the information needed to use it?

The exam is tomorrow (today is another)

Ouch. Been there. Good luck on your exams!

Sounds like fun! I’m going to bed soonish but I’m willing to answer questions about multivariable calculus probably when I wake up.

When I took multivariable calculus, the two books that really helped me “get the picture” were Multivariable Calculus with Linear Algebra and Series by Trench and Kolman, and Calculus of Vector Functions by Williamson, Crowell, and Trotter. Both are on LibGen and both are cheap because they’re old books. But their real strength lies in the fact that both books start with basic matrix algebra, and the interplay between calculus and linear algebra is stressed throughout, unlike a lot of the books I looked at (and frankly the class I took) which tried to hide the underlying linear algebra.

I’m autistic too and I had to relearn math as an adult. Now I know calculus and advanced mathematics.

I can go find some book recommendations, but when I was first learning I really got a lot out of watching The Organic Chemistry Tutor.

Linear algebra (ex: multiply the matrices A and B), multivariable calculus (example: find ∇F with F=[xy,yz,xz]^T ), or actual “multidimensional analysis” (example: define the norm of [1m,1m/s,1m/s^2 ] in a way that makes sense)? I can help with all three.

*moving, not motion.

If your signal looks like f(t) = K•u(t)e^at with u(t) = {1 if t≥0, 0 else}:

• If Real(a) > 0, then your signal will eventually blow up.
• If Real(a) < 0, then you signal will not blow up. In fact, your signal will have a maximum absolute value of |K|, and it will approach zero as time goes on.
• If Real(a) = 0, it is either a complex sinusoid or a constant. In either case, it is bounded with maximum absolute value of |K|. It very much does not blow up.

So e pops up all the time in stable systems and bounded signals because the function e^at solves the common differential equation dx/dt = ax(t) with x(0)=1 regardless of the value of a, particularly regardless of whether or not the real part of a causes the solution to blow up.

way more than $π million.

I don’t need more than $π million. I just need enough to get some stuff started. I’m not interested in getting rich.

I would also use the first loop to take medical tests of my health as much as possible since it wouldn’t matter if I went into debt in the first loop.

Fair enough, but I really need the charm. I’m autistic and I’m not good at being social. I’d definitely be willing to give up a few years of life for more charm.

get π million dollars and get +3 on all charm. This would actually help me dramatically.

Me reading about nonlinear dynamical systems 💀

Tbh if you just want to get started making music, you can hack it without theory. Theory will make you a more creative composer, but IMO don’t make it a strict prerequisite.

Look closely at the map: the water is in the country labeled Atlantic Ocean.

Well I just tried #define int void in C and C++ before a “hello world” program. C++ catches it because main() has to be an int, but C doesn’t care. I think it is because C just treats main() as an int by default; older books on C don’t even include the “int” part of “int main()” because it’s not strictly necessary.

#define int void replaces all ints with type void, which is typically used to write functions with no return value.

Running #define ; anything yields error: macro names must be identifiers for both C and C++ in an online compiler. So I don’t think the compiler will let you redefine the semicolon.

Reddit --> Lemmy

Facebook --> fucking nothing lmao

YouTube --> FreeTube + Invidious [1]

Windows --> Debian [2] with KDE Plasma

Word --> LyX

Microsoft Office --> LibreOffice

Built-in phone music player --> Odyssey [3]

Firefox --> LibreWolf [4]

Adobe Reader --> Okular + Librera on Android

Default phone launcher --> KISS Launcher

[1] I prefer FreeTube on computers where I have it installed, but one of my family’s jank 10-year-old work PCs can’t handle it, so I’ll typically watch videos in Invidious in LibreWolf on that computer.

[2] I can’t recommend Debian for absolutely everyone since it prioritizes stability and predictability over new features and ease of use, but it’s great for most of my use cases. I typically recommend Linux Mint for complete beginners.

[3] It handles extremely large music libraries (>100 GB of .mp3 files) without constantly taking forever to reload when I add a single new album.

[4] Firefox is pretty good and FOSS, but LibreWolf comes with better defaults and I’m a lazy fucker.

RIP in spaghetti, never forgetti

Only one way to find out

For anyone wondering, this is from /r/photoshopbattles. Excellent shitpost.

I mean how else are you supposed to unclog your cock?

Actually, you might need an extra ticket in case you have access to a time machine and go back in time to watch the show a second time.
