LimitBelow Command

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).
