LimitBelow[ <Function f>, <Value t> ]
Computes the left one-sided limit of the function f for given value t of the main function variable.
Example:
LimitBelow[1 / x, 0] yields -\infty .
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 .
Note:
  • Not all limits can be calculated by GeoGebra, so ? will be returned in those cases (as well as when the correct result is undefined).
  • See also Limit Command and LimitAbove Command.
