?can you spot any errors in my work? {implicitly differentiate y with respect to x} y=ln(xy) dy/dx=[x(dy/dx)+y*1] / [xy] -multiply both sides by (xy) xy (dy/dx) = x(dy/dx)+y -sutract x(dy/dx) form both sides xy(dy/dx)-x(dy/dx) = y - factor out dy/dx from the left then divide both sides by (xy-x) dy/dx= y/(xy-x) -siplify the right side by facoring out an x dy/dx=y/x(y-1)

    it should be . y/(x (-1+y)). which coincidentally is that. so good job :)
