What is the current when time = 2 seconds?

The charge q on a certain capacitor in an amplifier circuit as a function of time t is given by:
just to be clear π= pie
q = e-0.1t (0.2 sin 120πt + 0.8 cos 120πt)
the current i in the circuit is the instantaneous time rate of change of the charge. what is the current when time = 2 seconds?
