2. The nonlinear pendulum is governed by the equations de dv g sin e dt dt L 1 Solve using a) forward Euler and b) backward Euler for L 9m, At = 0.1s, vo = 0.6ms Integrate for 25s and plot v as a function of t. Comment on your results. Note that if a scheme is implicit, you may have to iterate to convergence at each time step. Use your own judgement on how best to do this and 0o 0.
