For Example i have a function f(x) and i should compute f'(x0); is it possible do it in a single command without compute f'(x) and then evaluate the function f'(x) in x0?
===============================
I might be missing something. Are you saying that you want to evaluate a derivative of a function at a point, but want to do it without evaluating the derivative?
I do not think this is possible? How can one evaluate something without evaluating it?
But to do it if we are allowed to evaluate the derivative, then one way is
f[x_] := Sin[x]
D[f, x] /. x -> Pi
