The differential1) sen(x+y)?

    Here are a few functions. I cant found the differential

    1) sen(x+y) = 2y - arctan y

    2) (e^(x-y)) (x-y) = log e

    These are clearly homework questions, and so we ask that you show work before we can help you. What do you think?

    In fact, in addition to showing us what you have tried, it would be a good idea to tell us what it is you are trying to do! Those aren't functions, they are equations. Do you want to find the partial derivatives of each side or what?
