[SIZE="7"]i want any thing to help me to solve the frequency response problems ,,because i need to answer for if the places of the resistors is stable or not i mean the general form of the circuit and resistance ,,also i want any solved problem to help me in that field
and thank you alot

What kind of frequency response problems? do you mean that the placing of a component is stable or not?
That is a very complicated question and only very advances software can analyze that.

The question is not clear

yes sir i mean the frequency response for amplifier (mid band,high frequency & low frequncy) and i want to solve a problem so just i need to know if the resistance place is stable or not;
thank u for care

That means an audio amplifier, the placing in audio amplifier is of little effect unless we have a very high input impedance amplifier and also a high gain.
In audio amplifiers the decoupling filters seem to have more effect than the placing of components.
In high frequencies where track/wire length contributes to wave length, and with tuning coils, placing is significant and like I said only sophisticated software can analyze that
The common rules for amplifiers are
Keep tracks/wires as short as possible
put enough decoupling filters
do not put components than can affect each other near by
if you have coils that should not interact make them perpendicular to each other
use shielding where electrostatic field is expected
