10.7.3  Denominator

The getDenom command finds the denominator of an unreduced rational function.

Unlike denom (see Section 10.7.4), textttgetDenom does not simplify the expression before extracting the denominator.

Examples

getDenom((x^2-1)/(x-1))
     
x−1           
getDenom((x^2+2*x+1)/(x^2-1))
     
x2−1
