Predefined Functions and Operators
From GeoGebra Manual
To create numbers, coordinates, or equations using the Input Bar you may also use the following pre-defined functions and operations. Logic operators and functions are listed in article about Boolean values.
Note: The predefined functions need to be entered using parentheses. You must not put a space between the function name and the parentheses.
