4 problems I can't figure out:

1) (x^2)(y^2) - y = x

2) 2sinx(cosy) = 1

3) sinx = x(1+tany)

4) y = sin(xy)

Please don't simplify or try to isolate y from the beginning. =)

Only simplify to isolate dy/dx

I'm not sure why I just don't know where to start..I think I just don't know how to apply product rule with the y's..

Hm, but why is it 2y(dy/dx) instead of just 2(dy/dx)?
