LimitBelow Command

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).
