    I am given the circuit in the figure attached and asked to determine i_{o} as a function of v_{I}. Me and a few of my colleagues have been aruging over whether the correct answer is,

    i_{o} = \frac{-v_{I}}{R} or i_{o} = \frac{v_{I}}{R}.

    Could someone please check my analysis, I don't think I've done anything wrong.

    Thanks again!

    The analysis looks fine - all it means is that you've got the inputs reversed. The current will be positive when V1 is more positive than V2.
