(%i37) load(revert)$
(%i38) t : taylor(coth(x) - 1/x,x,0,9);
(%o38) x/3-x^3/45+(2*x^5)/945-x^7/4725+(2*x^9)/93555+...
(%i39) revert(%,x);
(%o39) (126117*x^9+118503*x^7+114345*x^5+121275*x^3+202125*x)/67375
Suggestion: Check revert on some simple cases. Revert might
be well-tested, but I don't know that it is.
