Looks like Maple in MC11 ignores the possibility of a being zero. In this case the result of Maple in MC11 is wrong!

Admittedly MC15's answer without this specific "assume" is wrong in the same sense, too 🙂

Maybe it's not so wrong...

Note that the taylor-series of exp(a*x) is 1+ a*x+a^2*x^2/2+...

so in (exp(a*x)-1)/a, the 1 is subtracted out by -1,the next term divided by a leaves x, and the following terms all become 0 when a=0.
