Just a suggestion... (1 Viewer)

[ND]

Why doesn't a mod put up a sticky explaining the notion used? It's usually pretty good, but occasionally there are some people who aren't familiar with computer-maths notation, which can lead to confusion (and unnecessary complexity). Just a suggestion...

OK ...

Here are some Usual ones

a^b means a to the power of b
|x| means the absolute value of x
/ means divide
* means multiply
>= means greater than or equal to
<= means less than or equal to

sqrt(x) means the squareroot of x

cbrt(x) means the cuberoot of x, but I don't see this often.

Exp(x) is sometimes used in place of e to the power of x, although this is rare.

arcsin(), arccos(), arctan() are the inverse sine, cosine and tangent functions.

Always use brackets to avoid abiguity.

How about, we all have a thread with a list of people that wants themselves to be available to be contacted for maths questions? (icq, msn) etc

Since trial is coming soon, i'd have no problem sparing 15 minutes doing some maths question, since I need practice before the trial, and more importantly, the HSC, comes.

I think it is best to have the problems posted on this board, because more of us can read it, learn from them and/or correct any errors.

I agree with Affinity. Also, while i am happy to help out (where i can), there are some days where i'm too busy (or just not in a maths mood) to answer.
