Hello everyone. This problem has 4 parts. I got part (a) which is suppose to be the hardest part but i'm confused on how to (b) Plot Qn(t) for n = 1...4 observe wether the iterates seem to be converging. Well this is the series solution I got for the differential equation: http://img267.imageshack.us/img267/9578/lastscan6nh.jpg [Broken] Here is the orginal problem and how i got the answer to part (a). http://img251.imageshack.us/img251/7346/lastscan3rl.jpg [Broken] They also say: Plot |Q(t)-Qn(t)| for n = 1...4. For each of Q1(t),...,Q4(t), estimate the interval in which it is a reasonably good approximation to the actual solution. A few people asked the professor and he said, solve the Differential equation and hats the answeR? urnt?
