Consider the CD equation
ut −0.02uxx +0.1ux = 0, (4.17)
with initial condition u(x,0) = e
1.17712434446770x
. The exact solution of this equation is u(x,t) = e
1.17712434446770x−0.09t
.
Tables 1 and 2 show the errors of the approximate solution at different points (x,t). Also, the error function is shown
in Fig. 1 when t = 0.1.
