Downloaded wxMaxima a few days ago and trying different things. Asked for Taylor polynomial for e^x: (taylor, e^x, x, 0, 8) and got the following output:

1 + log(e)x + log(e)^2 x^2 / 2 + ... Oh well, seems like Maxima is fairly sophisticated package and yet I would expect 1 + x + x^2/2 ... just what you get from commercial packages.
