Okay so I have this problem. y'' + y = g(t) for y(0) = 0, y'(0) = 1 g(t) = {t/2 for 0 = 6} I really have no idea where to start for this. I've been really stuck trying to comprehend this topic and the textbook has no good examples for something like this. How would I find an equation for g(t) and Y(s)? Thanks D:
