    Hi, I need help for this derivative problem;

    Find dy/dx in terms of x and y for:

    xy = tan(xy)


    Any help is much appreciated,

    Differentiate implicitly.

     \frac{d}{dx} (xy) = x\frac{d}{dx}(y) + y\frac{d}{dx}(x)

     \frac{d}{dx} \tan(xy) = \frac{d}{d(xy)} \tan(xy) \times \frac{d}{dx}(xy)
