I see no interest, why ?
cos(x) is coded in Windows on Padé normalized rational fraction,
lot more stable and free of Taylor obsolete expansion.
If you insist, will check your curiosity.

I just want to know how in the Smath, and cos(x) is just a simple example, it doen't necessarily mean I will use Taylor series for cos(x).

I found Taylor, but I don't know why it doesn't work.

Hi. First, because "Taylor" isn't the maple command, it is "taylor", in lowercase. Second, because maple returns the answer with an "O" notation. You can use convert/polynom to get a result that SMath can handle.

SMath' maple plugin use version 6; here you can find two maple manuals, but for maple 7: https://www.maplesoft.com/documentation_center/history.aspx

Best regards.
