"Largest interval where solution is continuous" I have a gripe with the way I am being asked to do this. I am given a DE and asked to select the "largest interval of t where the solution is continuous." A: (0,1) B: (5, infinity) C: (-2, 0) D: (-8,14) Etc But all intervals of t are obviously the same size. So wtf are they asking? The largest interval assuming I am 12 and don't understand the cardinality of the real numbers?
