Forward and Backward Euler Methods. Let's denote the time at the nth time-step by tn and the computed solution at the nth time-step by yn, i.e., . The step size h (assumed to be constant for the sake of simplicity) is then given by h = tn - tn-1.

Astilbe is easy to grow, and is very tough and hardy. One of the beauties of them is that they do equally well in part sun or partial shade and will flower in either location.
