Current and voltage in AC circuits without impedance

How can we find the equation of current and voltage of a capacitor circuit if the input voltage is AC **without** using the impedance formula Xc = -jωC?.

We have for homework to find the equation of current of the circuit and the equation of voltage of the capacitor assuming we just connected the voltage source to the circuit

We can say that Ic = C1*dV/dt and Vc = Vo(0)+∫I(t)dt and from Ohm's law we can say that dV/dt = d/dt(V1-IR1) but what is the value of I?
