The solver seems to have a problem with some sets of boundary conditions. (See attached worksheet.)

Is there a way to get this numerical solution?

I would like to plot results that combine numerical solutions from odes with polynomials (from a collocation procedure). Here is the part of the worksheet:

What is the best way to plot the approximate solutions here? 

Thanks.

Hello. I tried to plot simple functions in MAPLE 16 and received this message:

Error, (in plot) unknown optional arguments [true]. I am not sure what the problem is and would appreciate any help. I have included an example below. Thanks.
