Waveform of voltage and current thru capacitor! Someone pls answer immediately! circuits!!

In the circuit, the sinusoidal sources are
is = 10xcos ?t A, vs = 100?cos ?t V,
where ? = 50 krad/s. Use the network analysis technique of your choice to find the waveform of the voltage v(t) and of the current through capacitor iC(t).
