i need help pls..

Transfer function

Can someone please help me with this problem:
a) Try to decide the transfer function H(jω) for this:
**broken link removed**
vin(t)=Acos(ωt) and H(jω) =Vout/Vin
I have count that C and R2 to R2/(jωR2C+1)
From here I dont know what to do

b) What is H(jω) if A->∞

thanks in advance

write the nodal at the top of v1 then sub in vout =-Av1
I redid to show results without plugging the math. Hope it get you started
I let z1=r1 and z2 =r2 in parallel with c

You are AWESOME thank you so much I get it now
