## Question:How to plot the figure at time

Dear maple users,

Greetings.

In this code, the problem has executed. But I unable to get the graph.
Kindly do the needful to plot the figure at time t=0.45.
Also, please explain how to import the computed values into an excel file.

Waiting for your reply.JVB.mw
