Dear group, I had prepared some tutorial for teaching elemental differential equations. These tutorials work fine in Math 5.0.0 and previous versions. However, using Mathematica 5.0.1 I have some problems with the same examples. Here is one of them DSolve[{c'[t] == a - b*c[t], c[0] == c0}, c[t], t]. I receive this message: "For some branches of the general solution, the given boundary conditions lead to an empty solution" Any suggestion? Guillermo
