- LimitBelow[ <Function f>, <Value t> ]
- Returns left one-sided limit of the function f for given value t of the main function variable.
Note: Not all limits can be calculated by GeoGebra, so undefined will be returned in those cases (as well as when the correct result is undefined).
CAS Syntax
- LimitBelow[ <Expression f>, <Value t> ]
- Computes the left one-sided limit of the function f for the given value t of the main function variable.
- Example:
LimitBelow[1 / x, 0]yields -\infty .
- LimitBelow[ <Expression f>, <Variable v>, <Value t> ]
- Computes the left one-sided limit of the multivariate function f for the given value t of the given function variable v.
- Example:
LimitBelow[1 / a, a, 0]yields -\infty .
