Maxima always prefers to find exact symbolic solutions. This is a
transcendental equation and has no exact symbolic solutions, so Maxima gives
up (in what sense does it "make Maxima swear at you"?)
So you should take a look at the documentation for numerical solutions,
assuming that when you say "define" e, Re, D, you mean assigning them a
specific numerical value. Try
for more information.

How do I properly define the equation and solve for f once I have defined e,
