Type this See that Comment
x^2+y_1+z_12^34 `x^2+y_1+z_12^34` subscripts as in TeX, but numbers are treated as a unit
sin^-1(x) `sin^-1(x)` function names are treated as constants
d/dxf(x) = lim_(h->0)(f(x+h)-f(x))/h `d/dxf(x)=lim_(h->0)(f(x+h)-f(x))/h` complex subscripts are bracketed, displayed under lim
f(x) = sum_(n=0)^oo (f^((n))(a))/(n!)(x-a)^n `f(x)=sum_(n=0)^oo(f^((n))(a))/(n!)(x-a)^n` f^((n))(a) must be bracketed, else the numerator is only `a`
int_0^1f(x)dx `int_0^1f(x)dx` subscripts must come before superscripts
[[a,b],[c,d]]((n),(k)) `[[a,b],[c,d]]((n),(k))` matrices and column vectors are simple to type
x/x = {(1,if x!=0),(text{undefined},if x=0):} `x/x={(1,if x!=0),(text{undefined},if x=0):}` piecewise defined functions are based on matrix notation
a//b `a//b` use // for inline fractions
(a/b)/(c/d) `(a/b)/(c/d)` with brackets, multiple fraction work as expected
a/b/c/d `a/b/c/d` without brackets the parser chooses this particular expression
((a*b))/c `((a*b))/c` only one level of brackets is removed; * gives standard product
sqrt sqrt root3x `sqrt sqrt root3x` spaces are optional, only serve to split strings that should not match
<< a,b >> and {:(x,y),(u,v):} `<< a,b >> and {:(x,y),(u,v):}` angle brackets and invisible brackets
(a,b]={x in RR | a < x <= b} `(a,b]={x in RR | a < x <= b}` grouping brackets don't have to match
abc-123.45^-1.1 `abc-123.45^-1.1` non-tokens are split into single characters,
but decimal numbers are parsed with possible sign
hat(ab) bar(xy) ulA vec v dotx ddot y `hat(ab) bar(xy) ulA vec v dotx ddot y` accents can be used on any expression (work well in IE)
bb{AB3}.bbb(AB]. cc(AB).fr{AB}.tt[AB].sf(AB) `bb{AB3}.bbb(AB].cc(AB).fr{AB}.tt[AB].sf(AB)` font commands; can use any brackets around argument
\stackrel"def"= or \stackrel{\Delta}{=}" "("or ":=) `\stackrel"def"= or \stackrel{\Delta}{=}" "("or ":=)` symbols can be stacked
{::}_(\ 92)^238U `{::}_(\ 92)^238U` prescripts simulated by subsuperscripts
