Dear mathgroup, I have been trying to solve the following equation using Solve, When I type in the following line I get a message saying that an illegal operation has been performed. f[w_]: = 1./(w^2) + (.9/30.)/(w - 2. Sqrt[200./10.]k)^2 - 1.- (3./30.)/( Sqrt[200./10.]k^2 ) Solve[f[w]==0., w] Can anyone tell me what I am doing wrong. My aim is to generate a set a roots,w , which is a function of k.
