- If you use TeX notation, probably most people on the net will understand
- you. A complete list is given in
-
- Donald E. Knuth, The TeXbook, Addison Wesley
-
- Just some of the most important rules
-
- _ preceeds a subscript
- ^ preceeds a superscript
- greek letters are written \alpha, \beta, ... and \Alpha, \Beta, ...
- quantifiers are \forall and \exists
- most standard functions (like the trigonometric ones) are preceeded by
- a \
- Curly braces {,} are used for grouping
-
- For example, you may write
-
- \int_0^{2\pi} \sin x dx = 0
- \forall x \sin^2 + \cos^2 = 1
-
- For nxn matrices A, B, C, we have C = AB if
-
- C_{ij} = \sum_{k=1}^n a_{ik} b_{kj}
-
-
- etc.
-
- Hope this helps.
