I solved a 2nd degree taylor polynomial using Matlab and checked it in Maple:

The function f (x) was: => x * e ^ x, at a = -1

Maple gives me Tn(x) = -1/e+....

I do not wish to write it all out here but will state that it give me ln

If I do the same using Matlab, it gives me the same answer but says log instead of ln.

Which one is right?

(On some other posts I read folks saying that ln and log) two different things!
