Hello calc. Use the red link under the banner to launch the latex editor. It has many advanced functions and it's output can be quickly saved as a .gif or .png for posting to this board.

I'm looking for a "cheap algebraic trick" here, but say I have a fraction like 23/75, are there any methods to "reasonably" get an approximate single digit ratio equivalent? In this case, I can eye it up and say "okay, about 25/75, so 1/3," but I'd like a less intuitive approach to this, for when it's not so obvious.

hey /calc/

why is math so hard for me?

no matter how much i try i just don't get it and it's annoying and it makes me RAGE

why is that?

This may seem like a very childish question,
but what is so important about pi other than finding the area of a circle and the fact that it's irrational and goes on forever?

Does anyone know why Psubscript2 = (1+3) = 2^2?

Hey, so for our final we have to learn the Taylor series. They only gave us about a week to learn it and I still feel confused about this. Do you guys have any tips for Taylor series in general or some links to check out?

I was just outside, smoking a cigarette and watching cars pass by on the street inf ront of me, when I saw a not-too-common sight here in Chicago (at where I stay): a very shiny and nice looking car, stark silver paint with larger-than-average wheels capped with those chrome wheel centers that are very popular with people who have enough disposable income to spend on those kinds of things.

After it passed, it made me wonder: does a larger wheel apply to a greater distance passed with the same output of energy from an engine or is it entirely dependent on the engine itself? Or are there other factors to consider? I figure this was more appropriate to /calc/ than /sci/, but I'm really a layman when it comes to the more cognitive arts.

Suppose you were living on the surface of a torus so large that it would be impossible for you to move appreciably in any direction. Is there any way to determine the shape of your world with a test which could be conducted "localy".

Why is this?
