that's the way I do it, Hacker's way is to write [math]\not =[/math] if that helps you to remember

Here are a few more LaTeX codes you may enjoy ... or not.

\circlearrowleft . $\circlearrowleft$ . . . \circlearrowright . $\qquad\circlearrowright$

\curvearrowleft . $\curvearrowleft$ . . \curvearrowright . $\curvearrowright$

\rightsquigarrow . $\rightsquigarrow$

\bar{x} . $\bar{x}$

\langle . $\langle$ . . . . \rangle . $\rangle$

\hdots . $\hdots$ . . \cdots . . $\cdots$ . . \ddots . $\ddots$

\pmod{n} . $\pmod{n}$

\boxed{x = 1} . $\boxed{x = 1}$

9\choose3 . $9\choose3$ . . . \binom{9}{3} . $\binom{9}{3}$

\! . removes a space
. . \sin^2x + \cos^2x produces: $\sin^2x + \cos^2x$
. . . . . . . . . . . . . . . . . . . . . . . . . . $\uparrow$ . . . . $\uparrow$
I found that the extra spaces can be confusing.
They can be removed with: \sin^2\!x + \cos\!x: . $\sin^2\!x + \cos^2\!x$

Thanks! That can be useful.

Can someone show me how to make a Pascals triangle with LaTex code? Creating a new row with \\ wont work if I'm not creating a matrix or something similar with surrounding things.

Sorry, your Web browser is not Java compatible. This prototype will not be of much interest to you.

Type in: [draw]Point (100,80); Point (50,200); Point (150,200); Segment (1,2); Segment (1,3); Segment (2,3); Midpoint (4) [hidden]; Midpoint (5) [hidden]; Midpoint (6) [hidden]; Segment (7,8); Segment (7,9); Segment (8,9);[/draw] to get the picture at right.

oops, you wanted Pascals triangle

, I gave you sierpinski (however that's spelled)

type in:
[code]
1
1 1
1 2 1
1 3 3 1
1 4 6 4 1
1 5 10 10 5 1[/code]

to get:

Code:

          1
        1   1
      1   2   1
    1   3   3   1
  1   4   6   4   1
1   5  10   10  5   1

Ok thanks, doing it with code tags seems simple.

Code:

\sqrt{ \frac{2x+7}{8x+4} }

To get,
$\sqrt{ \frac{2x+7}{8x+4} }$

How do you make a degree-sign? Like a $\circ$ but higher up...

I think there is an actual LaTeX code for it, but I just do ^o (The "o" is just a lowercase letter o.)

$20^\circ$

Just write <math> ^\circ <\math>

Smart! And what about an accordingly/therefore/consequently/thus sign? (what is the English name for it?) It is suposed to look like three points in a triangle.

I tried [math]\therefore [\math] and [math]\because [\math] which are actually LaTex code for those symbols but as you can see they don't work here.
