- Numerator[ <Function> ]
- Returns the numerator of the function.
- Example:
Numerator[(3x² + 1) / (2x - 1)]
yields f(x) = 3x² + 1.
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[a + b/c]
yields a c + b
Note:
- For a fast numerical method (so long as the numbers aren't too big) you can use these in the Input Bar:
CommonDenominator[a,a]
for denominator andround(a*CommonDenominator[a,a])
for Numerator. - See also Denominator Command.
