Online Algebra Calculator
Many of users do not use powerful Maxima computer algebra system for systematic work, but for ad hoc algebraic calculations – equations, functions, matrixes, etc. only. To do this job, it is not useful to download the whole application from a web site.
Function: denom (<expr>) Returns the denominator of the rational expression <expr>.
![Denom Example f(x):=(x^2-1)/(x^2+1);
solve(f(x)=f(-x),x);
denom(f(x));
solve(%i3=0,x);
limit(f(x),x,inf);
diff(f(x),x,1);
solve(denom(%06),x);
plot2d(f(x),[x,-10,10]);

There are also some inexact matches for denom. Try ?? denom to see them.
