hello, i am new to electronics and i am having trouble trying to calculate the mid-band voltage gain vo/vi and the lower and uppper -3 dB frequencies for this circuit, when i do the small signal para's and use the ac model, i cant get any reasonable values to come out.

i figure out the q-points to be

Vce1 = 4.6V Ic1 = 1.011mA

Vce2 = 4.98V Ic2 = 1.0043mA

i figure out the q-points to be

Vce1 = 4.6V Ic1 = 1.011mA

Vce2 = 4.98V Ic2 = 1.0043mA
