http://www.math.iup.edu/~clamb/class/math341/2.7-forward-euler-method/ WebThe Forward Euler method is an explicit method, as the RHS depends on previous iterates. In contrast, the Backward Euler method, \begin{align} y_{n+1} &= y_n + f(t_{n+1},y_{n+1}) \end{align} is an implicit method. Question 1. Why may it be useful to have a computational scheme for computing solutions?
