- Numerator[ <Function> ]
- Returns the numerator of the function.
- Example:
Numerator[(3x² + 1) / (2x - 1)]yields f(x) = 3x² + 1.
- Numerator[ <Number> ]
- For a rational number returns its numerator. It uses a numerical method, which limits this command to numbers with small denominator. For irrational input the numerator of its continued fraction is returned.
Note: See also Denominator Command and FractionText Command.
CAS Syntax
- Numerator[ <Expression> ]
- Returns the numerator of a rational number or expression.
- Examples:
Numerator[2/3 + 1/15]yields 11.- If variables a, b and c haven't been previously defined in GeoGebra, then
Numerator[a/b]yields a andNumerator[Simplify[a + b/c]]yields a c + b
