Limit Command
From GeoGebra Manual
- 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.
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).
- If you want the limit of a piecewise-defined function you need to use LimitAbove or LimitBelow, for example
LimitAbove(If(x>1, x^2, -2x), 1)
