Alternating current?
Fujimoto: what exactly is your question? Assuming you are adding three terms if current, I suggest vector addition - convert from polar coordinates at t=0 to cartesian coordinates and add the vectors, then convert back to polar and determine the resulting magnitude and phase angle. You can do this since omega is the same for all three.
