We solve it by Euler's method using mesh size . We compute and the results are tabulated as follows:

We can notice that overflow occurs because for this problem and so with the error is amplified by at each step. In 100 steps, the error in the first step is increased by nearly in size. Once we find the computed solutions are meaningful and converge to the true solution. |
