# Thread: Maple versus matlab in seq and series'

1. ## 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

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.
