I was hoping to find a nice symbolic solution for the root of this equation:
a,c,d,k are parameters.
Unfortunately, I got an RootOf expression, which does not make sense to me. Assumptions do no help me further.
Next week, I have to present my results, but I don't know how to interpret is (the help file does not bring any relief). Is there something to say about the root? Suppose, I wanted to use side restriction on a problem? E.g., find a solution conditional on the fact that the derivative is zero.
Clearly, in the plot it seems simple.
In one case there is a solution Maple provides: a (a parameter)
This seems strange, because numerically there is one solution (and clearly not a).
