Approximating a solution that doesn’t exist (By:...
The following example made an impression on me when I first saw it years ago. I still think it’s an important example, though I’d draw a different conclusion from it today. Problem: Let y(t) be the solution to the differential equation y’ = t2 + y2 with y(0) = 1. Calculate y(1). If we use Euler’s numerical method with a step size h = 0.1, we get y(1) = 7.19. If we reduce the step size to 0.05...
