Fig. 4.5.
Solutions to (4.3) for T = 10 with a time step of 0.04 (left), 0.02 (middle), and 0.01 (right). Top plots: Yμ and yμ for time interval [9, 10]. Bottom plots: Φ and ϕ. The dotted lines indicate the corresponding exact solutions yμ and ϕ evaluated on the same time mesh as the dashed-lined numerical approximations Yμ and Φ.
