Mathematician Chat V.floor(π) - General

I waited for a while for some more knowledgeable user to create a thread, but nope. So I'm making it instead.

Most of the times [B]Wikipedia [/B]is all you need. I'm currently taking a Probability theory and Statistics course, pretty damn interesting and fun.

WolframAlpha has helped me infinitely while taking Calculus this year. Since it's essentially a self-teaching course with very few examples, being able to check my work is great. On another note, should I take Calc II in college y/n?

Depends what kind of major you're going for.

[editline]1st March 2013[/editline] I love math though, I would take any math course really

Can partial fractions be used for rational functions of infinite degree?

that is a funky looking pi in the title

Did Guass put pi and an integrand in his signature? [img]http://upload.wikimedia.org/wikipedia/commons/3/3f/Carl_Friedrich_Gau%C3%9F_signature.svg[/img]

The integrand might be a long s

That's exactly what an integrand is. He was probably being fancy but I still geeked out.

signatures sure were fancy back in the day

Oh hey is that a knot of some sort at the top of the integrand?

Happy pi month?

I'm 17 and I'm taking "Analys 1" right now, which translates to Calculus 1. I've heard that Calculus 1 is relatively very easy, but I'm not sure how the difficulty maps to the Swedish version of it. Anyway, I do find it hard in some areas. It's not very much that I don't understand it, it's just that there are so many things to memorize. For example, I have to memorize 8 standard integrals that I've never seen before. I also struggle a bit with memorizing some of the integration methods you have to memorize. It doesn't feel like so right now, but I'm actually pretty sure I will find all this stuff really easy once I've just concentrated on it a bit and connected some pieces.

Practice! Perfect practice, makes perfect!

[QUOTE=Bradyns;39772344]Practice! Practice! Practice! Perfect practice, makes perfect![/QUOTE] Actually, you know what? I just took a little break from the math, a walk outside. When I came back everything seemed a lot easier because I had already connected some of it. I'm pretty confident I'm going to get a good score on the test in two weeks.

Algebra was here, analysis is terrible

I like to use this when I need post problems here, you can use the created picture without having to upload it or anything [url]http://www.codecogs.com/latex/eqneditor.php[/url]

MATH!

Which of these statements are true? [url]http://gyazo.com/28720a9d237eb5dbf99a02bd27641313[/url] c and e?

sure looks like it

I got it now I think. This is true in only one point, right? [sp]x = i[/sp]

I'm so envious of you guys. I lack any sort of math education and Khan Academy is haaaard. I can hardly simplify fractions. And I can't do factorization. :(

[QUOTE=JohanGS;39794369]I got it now I think. This is true in only one point, right? [sp]x = i[/sp][/QUOTE] Well it's certainly true there, but that's not all. [sp]When a variable cancels out of an equation it means it can equal anything[/sp]
