Re: Part-time math hobbyist, I just took ODE. Any applications?

This may not be quite what you're looking for, but have you tried learning a programming language? Besides being a useful skill, if you try using it to model any real-world (or fantasy-world) scenarios, you'll have to wield your mathematics (especially ODEs where the physics come in to play). Of cou...

Re: ¡Hablamos español! (Spanish Practice)

¡Hola! Espero que no esté descarrilando una conversación importante; tengo una pregunta: ¿Cuáles son sus programas favoritas que ver online para practicar escuchar el español? A mi, me encanta La Vida Moderna de Rocko, mientras que Bob Esponja me resulta demasiado difícil por alguna razón. Y las can...

Re: An indefinite integral [solved]

Heh, oops. *improper.

Nah, regardless that it trumped me it is a pretty cool problem. And as it's an analysis course, it was a relief to see any computation problem. (Until, y'know, I wasn't able to compute it.)

Re: An indefinite integral

Ah, yup; much appreciated, t0rajir0u.

I feel unclever, seeing as the rest of the problem set was essentially "Here's Fubini's theorem, now hit things with it." I suppose once I decided the integrand was reminiscent of a derivative there was no going back.

An indefinite integral [solved]

After wrestling with considerably more intimidating challenges on my multivariable homework set, I was relieved to see my next problem was just a one-variable integral. Then it kicked my ass. \int_{0}^{\infty}\frac{\arctan(\pi x) - \arctan(x)}{x}\, dx Could somebody suggest a plan of...

Re: INTRO THREAD THE THIRD

Don't say that to anyone who's ever listened to music composed by set theory. That's for sure... I had to compose a twelve-tone piece for one of my finals this term. The outcome was not pretty. Which is not to say I've never enjoyed an atonal work, but I generally tend not to be crazy about the res...

Re: Uncountably many vertical asymptotes?

Ah, I figured I was making too bold a claim there. Mm, the Cantor set "draping" sounds like a good approach. As far as rigorously defining "vertical asymptote" on the real line, I was just working with t being a vertical asymptote (from the left) if \lim_{x \to t^-}f(x) =...

Uncountably many vertical asymptotes?

My friend and I were on the porch having a smoke and discussing mathematical oddities when he brought up vertical asymptotes, leading later to questions which I pose as follows: Consider a function f : E \to \mathbb{R} , where E \subset \mathbb{R} . Let A be the set of points at which the graph of f...

Re: INTRO THREAD THE THIRD

Hi there, I'm Larry. (Or Twelfthroot, I guess.) I'm an undergrad studying music composition and pure mathematics. For any desiring a hasty, convenient categorization, I suppose I'm a hippie-nerd. Without implying any competence, I love playing guitar, singing, writing, acting, coding, rom hacking, w...
