### Differential Equations and Us

Who knew that the last unit of AP calculus would be the best and the most fun. Granted it is difficult and the problems take up a page each, but it is definitely more interesting than the other units, probably because it relates to real life with the coroner problem and cooling problems. The hard part is when the problem has something like " the rate at which the population changes is directly proportional to the population at that time." Man that confuses me to no end. It is even harder when they a constant rate, because I'm not sure whether or not I should use that as k or make that number the coefficient of P and still include a k or not include a k. It's really hard sometimes, but at last were finished.

Hi Steve,
You mentioned “but at last we’re finished”. I am wondering if you’ve only just begun?? And if that could be so, your journey in calculus is just the beginning of ???
