Can someone help me with how to use Maple's DAE solvers? See the PDF file below with my attempt to solve a system of 2 differential and 1 algebraic equation. I can't go beyond the second solution (f2,p2). What does this error message below f3 line mean? If I start from the reset line again and skip f1,p1,f2,p2, then I can get solutions (f3,p3), and (f4,p4), but not in the sequence f1,p1,f2,p2,f3,p3,f4,p4. What am I doing wrong?
