- 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
