Briliant! It worked! Thank you very much.

If I could bother you a bit more, could you explain what the last 2 lines do?

I assume you somehow tell Maple that the solution is in that range and then give it a starting point to iterate i.e. solve numerically? But would this only work if the starting point is close enough to the actual answer? Or what if you don't know the range at all?
