How to find the derivative of       z    =    x          (              y        2            )        -          e              x        y            ?

We have:      z    =    x          y      2        -          e              x        y            Which has the derivatives; which is a function of two variables;                    ∂        z                    ∂        x              =          y      2        -    y          e              x        y                                ∂        z                    ∂        y              =    2    x    y    -    x          e              x        y            Remember when partially differentiating: differentiate with respect to the variable in question, treating the other variables as constant.
