| 输入 | 显示 | 说明 |
|---|---|---|
| \$x^2+y_1+z_12^34\$ | $x^2+y_1+z_12^34$ | 类似 TeX格式，数字当作一个整体处理 |
| \$sin^-1(x)\$ | $sin^-1(x)$ | 函数名当作常数处理 |
| \$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 |
| \$\frac{d}{dx}f(x)=\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}\$ | $\frac{d}{dx}f(x)=\lim_{h\to 0}\frac{f(x+h)-f(x)}{h}$ | 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,if x!=0),(text{undefined},if x=0):}\$ | $x/x={(1,if x!=0),(text{undefined},if x=0):}$ | 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\$ | $sqrtsqrtroot3x$ | 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 |
