+ - * : /
() [] {} |
Plus, minus, multiplication, division, grouping symbols.
Multiplication sign * is not necessary and can be omitted.
Examples: 0.5x^3-3x or pixeln(2cos[LN2x]) or Pipi/(Exe) Using different types of
grouping symbols (parentheses, brackets, braces) for clarity of
nested expressions is optional, but not necessary. |
base^exponent
or
p(base,exponent)
|
Exponentiation baseexponent, for example
p(x,2) or x^2 . Instead of ^ you can also
type a single quote ' or a double quote ". If you
don't use p(), make sure that bases or exponents composed by
sub-expressions such as additions, subtractions, multiplications or
divisions, are clearly marked off by being completely enclosed into
parentheses, brackets or braces. Example: (x/3)^(2x) . Instead of x"3, of course, you can also enter
xxx. Or, instead of tan(x)'2 you may type tan(x)tan(x). |
| root(arg,radic.exp.)

root(x,6) sixth root of x, root[tan(x),4] fourth root of the
