Electronics question , please help?

is it possible to get the voltage gain in an fet small signal analysis without vp

example if the yos =40micro simiens

Idss=8mA

vgs(off)=-4V

RG=10 Mega ohms

RD=2.2 KILO ohms

RS=750 ohms

and capacitor 1 is 0.05 micro farad and capacitor 2 is 0.05 micro farad.can you guy help me to calculate for VP..please?

    Assuming small signal conditions and the frequency is high enough that capacitors act as short circuits. (you didn't specify a frequency)

    Vgain = (2*RD*Idss)/Vp)

    Vp = vgs(off)

    Vgain = [2*(2.2E3)*8E-3]/-4

    Vgain = -8.8
