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).
