determine the derivative of tan^-1 (x/y) = x-y with respect to x. a. (x^2+y^2+x)/(x^2+y^2+y) b. (x^2+y^2-y)/(x^2+y^2-x) c. (x^2+y^2-x)/(x^2+y^2+y) d. (x^2+y^2+y)/(x^2+y^2-x)

OpenStudy (kainui):

I'd suggest rearranging the formula so that you feel most comfortable doing implicit differentiation. I'd much rather take the derivative of tan than arctan.
