    Implicit Differentiation of...

    I know implicit differentiation is simple, but I have hit a bit of a snag with some trig...

    Can anyone please tell me how to find dy/dx when;

    sin3xcos2y = 6


    I have gone as follows...

    3cos3xcos2y dy/dx - 2sin2ysin3x = 0

    Im all over the shop

    first post!
    thanks
