- Denominator[ <Function> ]
- Returns the denominator of a function.
- Example:
Denominator[5 / (x^2 + 2)]yields f(x)=(x2 + 2).
Notes:
- 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 Numerator Command.
- For a fast numerical method (so long as the numbers aren't too big) you can use these in the Input Bar:
