`x^2` or `a_(mn)` or `a_{mn}` or `(x+1)/y` or `sqrtx`| 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 |
| \`lim_(h->0)(f(x+h)-f(x))/h\` | `lim_(h->0)(f(x+h)-f(x))/h` | complex subscripts are bracketed, displayed under lim |
| \$lim_{h\to 0}\frac{f(x+h)-f(x)}{h}\$ | $\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}$ | standard LaTeX notation is an alternative |
| \`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 |
| \$f(x)=\sum_{n=0}^\infty\frac{f^{(n)}(a)}{n!}(x-a)^n\$ | $f(x)=\sum_{n=0}^\infty\frac{f^{(n)}(a)}{n!}(x-a)^n$ | standard LaTeX produces the same result |
| \`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,(x!=0 ÀÏ ¶§)),(text{Á¤ÀǾȵÊ},(x=0 ÀÏ ¶§)):}\` | `x/x={(1,(x!=0 ÀÏ ¶§)),(text{Á¤ÀǾȵÊ},(x=0 ÀÏ ¶§)):}` | piecewise defined function 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 |
| \`sqrtsqrtroot3x\` | `sqrtsqrtroot3 x` | spaces are optional, only serve to split strings that should not match |
| \`(:a,b:) and x lt y lt 1\` | `(:a,b:) and x lt y lt 1` | the < character is problematic in XML, use 'lt' or put formula in a comment |
| \`(a,b]={x in RR : a lt x le b}\` | `(a,b]={x in RR : a lt x le 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 |
