defining symbolic function

[Rama Kunapuli]

Need to define a generic function - say A(t) such that when I evaluate differential with respect to t, I should get A'(t) or dA/dt.

Is it possible to do this in Sage?

Thank you both for the directions Nils Bruin, Symbolic variables link really helped. The following code works;

t,A =var('t','A')
A=function('A',nargs=1)(t);A
A.derivative(t,1)

 Is it possible, to display A.derivative(t,1) with a dot notation \dot{A}  instead of \frac{\partial A}{\partial t}?
