From GeoGebra Manual
| This command differs among variants of English:
- Maximize( <Dependent number>, <Free number> )
- Calculates the free number which gives the maximal value of the dependent number. The free number must be a slider and the slider interval will be used as the search interval. The relationship should be continuous and have only one local maximum point in the interval. If the construction is complicated, this command might return ? to avoid using too much processor time.
- Maximize( <Dependent Number>, <Point on Path> )
Note: See also Minimize command.
