AasciiMath Reference
Syntax
Most AsciiMath symbols attempt to mimic in text what they look like
rendered, like oo for `oo`. Many symbols can also be
displayed using a TeX alternative, but a preceeding backslash is not
required.

Standard Functions
sin, cos, tan, sec, csc, cot, arcsin, arccos, arctan, sinh, cosh, tanh, sech, csch, coth, exp, log, ln, det, dim, mod, gcd, lcm, lub, glb, min, max, f, g.
Special Cases
Matrices: [[a,b],[c,d]] yields to `[[a,b],[c,d]]`
Column vectors: ((a),(b)) yields to `((a),(b))`
Augmented matrices: [[a,b,|,c],[d,e,|,f]] yields to `[[a,b,|,c],[d,e,|,f]]`
Matrices can be used for layout:
{(2x,+,17y,=,23),(x,-,y,=,5):} yields
`{(2x,+,17y,=,23),(x,-,y,=,5):}`
Complex subscripts: lim_(N->oo) sum_(i=0)^N yields to `lim_(N->oo) sum_(i=0)^N`
Subscripts must come before superscripts:
int_0^1 f(x)dx yields to `int_0^1 f(x)dx`
Derivatives: f'(x) = dy/dx yields `f'(x) = dy/dx`
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") yields `ubrace(1+2+3+4)_("4 terms")`.
obrace(1+2+3+4)^("4 terms") yields `obrace(1+2+3+4)^("4 terms")`.
Attention: Always try to surround the > and
< characters with spaces so that the html parser does not
confuse it with an opening or closing tag!
