    Hello everyone.

    Could anyone please try to explain how equation 1.10 comes about. I have tried using the superposition theorems but noting seems to be going for me.

    Any help would be greatly appreciated.

    The first half of the equation is the V+ voltage due to the input voltage with 0V at the output. The second half is the V+ voltage due to the output voltage with 0V at the input. You add the two together by superposition to get the equation shown.
