LimitBelow[ <Function>, <Value> ]
Computes the left one-sided limit of the function for the given value 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>, <Value> ]
Computes the left one-sided limit of the function for the given value of the main function variable.
Example:
LimitBelow[1 / x, 0] yields -\infty .
LimitBelow[ <Expression>, <Variable>, <Value> ]
Computes the left one-sided limit of the multivariate function for the given value of the given function variable.
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).
