my bad, actually, I have no idea how to start this homework. can you just give me some formula, or any hints to solve this, or where to focus on reading please. i only learned the basic stuffs like the types of amplifier, how its set-up but not when everything are combined and the mathematical part.

You've posted a screen shot with seven problems. Are you asking for someone to tell you how to get started on all seven? You have absolutely no idea how to begin ANY of these problems?

Hint on P1: Assume an arbitrary input signal, V(jw), and determine the output of the first opamp. Then, using that as the new input signal to the second part of the circuit, find the final output voltage.

Do you know how to calculate the gain of typical op amp circuits? If not here are some of the basics.
