Thanks!The symbol is beta, which is also commonly refered to as Hfe in junction transistors. Your device is a FET, so you use gfs to get the gain.
This may give you the steps to take - http://ocw.mit.edu/NR/rdonlyres/Ele...E1A7E3-8AAE-47B6-A759-309170DF888E/0/jfet.pdf.
It is solved now.There are no values given to the components in the circuit. Are you solving for DC or AC conditions?
