I dont understand how to add V1 and V2 up since one of them in sinus function while other is in cosinus form.What part do you not understand on this problem. Just break the problem up. This is a inverting op-amp, so use that formula. You can combine V1 and V2 with addition. If you have a more specific question, please don't hesitate to ask.
