Greeting everyone

I'm required to obtain the transfer function Vo/Vi for the Op Amp Circuit. I think I've gone about the right way but i have doubts so
I just want the feedback from others as to how it would be approached.

I Thank you all in advance for your thoughts...

... looking at this article on negative feedback op-amps ... see the section on inverting configuration:

https://www.allaboutcircuits.com/technical-articles/the-inverting-configuration-of-an-amplifier/

It looks like the Vo/Vi transfer function is basically a ratio of R2/R1 ... So if you make an analogy with your circuit, the desired transfer function would be the ratio of the R2C2 impedance to the R1C1 impedance. This operation requires some Z-Y manipulation, but should be tractable.

Nice I was thinking along the same lines, thanks for the reassurance. I'll check out that article thanks again
