I've always been able to count the limits of the sequences using Maple but  
I can't find a way to find a limit of even a simple function. Maybe  
someone could help me and tell me what command should I use.

Is there a straightforward way to differentiate basis vectors? For
example, when differentiating a vector in polar notation, I would like
the returned vector to have differentiated the basis also. Thus the
derivative of e[r]with respect to t is thetadot*e[theta] and the the

I'd like to have a kind of grid (horizontal and vertical lines ) in the
background of my ploted function.
Is this possible in Maple.

It would be reat to hear acommnets, especially from Maple experts
