Could anybody out there familiar with Maple tell me what is wrong with this command:
H := (F/(m^2*(sqrt((omega^2 - omega[0]^2)^2 + 4*alpha^2 * omega^2); ;

The equation I'm trying to read in is the one on this page .

P.s if anybody can give me any hints as to how to do the assignment I would greatly appreciate it cause I'm getting nowhere.
