i have tried to solve this problem. but, I dont know that is correct or not.
the problem is to find transfer function of P and Q in this pic.
and here my ans,
can someone correct my ans?

 

Isnt that correct?
Except usually you solve for Q so you have:
Q=P/Z
or maybe:
Q/P=1/Z

so my ans is correct? thanks for your reply

 

The product of three

so my ans is correct? thanks for your reply

No - it is not.
You have computet the input impedance, but not a transfer function which is the output-to-input ratio.

But how would one know what is the input and what is the output? The problem statement is, "... to find transfer function of P and Q in this pic." Is it reader's choice? Is the input driven by a voltage source or by a current source?

No - it is not the readers choice. The man who gave you the task description should specify
* input and output nodes,
* the source (voltage or current).

In your case, the transfer function "of P and Q" is wanted ....whatever this means.
Normally, the transfer function BETWEEN two ports is wanted.
