    Maple versus matlab in seq and series'

    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!

    Both, almost universaly in programming languages \log means natural log, also many mathematicians use this convention as default.

    In secondary education and some other places \ln is used for natural log.

    The use of \log without qualification for log to the base 10 is usually confined to secondary education.

    Another common notation is \lg for log to the base 2.

    Sometimes the base does not matter when \log is invariably used.

    Best to always specify the base.
