    This is question 2.78 out of Sedra/Smith Micro electronics textbook. (6th edition)

    I'm confused as to how the authour of my textbook draws this conclusion in his work. (I have it circled)

    By the way, in the given question we are analysising the circuit in the figure to demonstrate how it is a voltage to current converter regardless of the value ZL.

    Can someone explain?

    Thanks again!

    EDIT: My work up to the point where I am stuck has been posted as well.

    Can you post a image with higher resolution? I 'm having trouble reading the variable's indexes.

    I'm not sure how to do that, if you click zoom it becomes more clear.

    Bump, I've posted my work on the OP now as well.

    Hopefully we can figure out how he derived the term I circled in pencil in his solution.
