Limit( <Function>, <Value> )
Computes the limit of the function for the given value of the main function variable. (This may also yield infinity.)
Example: Limit((x^2 + x) / x^2, +∞) yields 1.
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

Limit( <Expression>, <Value> )
Computes the limit of the expression for the given value of the main function variable.
Example: Limit(a sin(x) / x, 0) yields a.
Limit( <Expression>, <Variable>, <Value> )
Computes the limit of the expression for the given value of the given function variable.
Example: Limit(a sin(v) / v, v, 0) yields a.
