+ - * : /
() [] {}
|
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).
