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

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


\circlearrowleft . . . . \circlearrowright .

\curvearrowleft . . . \curvearrowright .

\rightsquigarrow .

\bar{x} .

\langle . . . . . \rangle .

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

\pmod{n} .

\boxed{x = 1} .

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

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

How do you make a degree-sign? Like a 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.)

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