i understand the main concept of differentiating implicitly, however i cant seem to get this problem,
sin(xy)=6x+7
can someone please help me with this one...much thanks...

i have just one more, about implicity differentiation...for this problem...
x^3 + 5x^2y + 2y^2 = 4y + 11
the last answer i came up with was...
(-3x^2-10xy)/(5x^2+4y-1)
then it wanted the slope of the tangent line at (1,2), but when i plugged these in the answer was wrong, and im sure thats from a faulty differentiation, can you please let me know where i messed up...thanks
