On ex.5 at 16:00, adding the numerator terms requires multiplying the first term by sin y/sin y and therefore should be sin x sin^2 y. Right?

For the problem: x + sin(x) = (x^2)(y^2), this is the work I did:

1) 1 + cos(y)(dy/dx) = 2(x^2)y(dy/dx) + 2x(y^2)

2)(dy/dx)(cos(y)-2(x^2)y) = 2x(y^2)-1

3)(dy/dx) = (2x(y^2)-1)/(cos(y)-2(x^2)y)

Would this be correct too? (Sorry if it looks unclear here)

For the second order example, why is it 4(8y+1)^2 in the beginning of the final answer? Shouldn't it start with 4(8y+1)?
