Syntax

Most AsciiMath symbols attempt to mimic what they look like when presented in text. oo For ‘oo’. Many symbols can also be displayed using the TeX option, but the preceding backslash is not required.

standard work

sin, cos, tan, sec, csc, cot, arcsin, arccos, arctan, singh, cosh, tan, sech, csh, coth, exp, log, ln, det, dim, mod, gcd, lcm, lab, glb, min, max, f, g.

special cases

Matrix: [[a,b],[c,d]] `yields to[[a,b],[c,d],

Column vectors: ((a),(b)) `((a),(b))` is obtained

augmented matrix: [[a,b,|,c],[d,e,|,f]] `yields to[[a,b,|,c],[d,e,|,f],

Matrix can be used for layout:
other left brackets
r ::= ) yields `: `

Complex subscript: lim_(N->oo) sum_(i=0)^N `lim_(N->oo) sum_(i=0)^N` is obtained

The subscript must come before the superscript:
int_0^1 f(x)dx `int_0^1 f(x)dx` is obtained

Derivatives: f'(x) = dy/dx `f'(x) = dy/dx` we get
For variables other than x,y,z, or t you will need grouping symbols:
(dq)/(dp) For `(dq)/(dp)`

Overbraces and underbraces:
ubrace(1+2+3+4)_("4 terms") Produces `ubrace(1+2+3+4)_(“4 terms”)`.
obrace(1+2+3+4)^("4 terms") `Obrace(1+2+3+4)^(‘4 terms’)` is obtained.

Note: Always try to surround > And
< Characters with spaces so that the HTML parser doesn’t confuse it with opening or closing tags!

grammar

Here is a definition of the grammar used to parse AsciiMath expressions. In the Backus–Naur form given below, the letter on the left
::= Represents a range of symbols that can be one of the possible sequences of symbols listed at right. vertical bar | differentiates the options.

v ::= [A-Za-z] | greek letters | numbers | other constant symbols
u ::= sqrt | text | bb | other unary symbols for font commands
b ::= frac | root | stackrel | other binary symbols
l ::= ( | [ | { | (: | {: | other left brackets
r ::= ) | ] | } | :) | :} | other right brackets
S ::= v | lEr | uS | bSS             Simple expression
I ::= S_S | S^S | S_S^S | S          Intermediate expression
E ::= IE | I/I                       Expression
