@Herschel Peeler : You're free to do as you like, it's your choice.

However, we don't want to disencourage you. Your help is welcome. All we ask is that you back off a bit within the homework section. In this section it is our policy to guide the op to find his own solution, not to give it to him. Only by understanding the problem and the way to solve it will the op be able to learn from the thread and to solve similar topics in the future by himself.

In this thread, for example, one way would have been to hint at V+ - V- = 0 V at the opamp's input and to solve the resulting node and loop equations. Another hint was given by Steve about the resistor

__ratio__. Thus the op would be able to find the transfer function for other opamp based circuits by himself. Giving the equation for this particular circuit will allow him to compute the result, but he will be at a loss when the circuit changes.

I know, sometimes it is hard to restrain oneself, especially when the answer seems to be so obvious to the experienced eye. But keep in mind we all had to learn sometime and 'learning by doing' is still one of the most efficient methods (in my opinion).

Harald
