Please explain each part in order as I'm totally confused. For part d I have to use the existence and uniqueness theorem

2. Consider M(x, y) + N(x, y) · = 0. (a) Suppose we can find a function F example of such an equation and solve it. F(x, y) so that F = M and F,: = N. Give an (b) Suppose we can find functions u and z so that (uo z)(x, y) is an integrating factor that transforms the given equation into an exact equation. What must be true about M and N? (c) Continuing from part (b), suppose we can find functions u and z so that (uoz)(x, y) is an integrating factor that transforms the given equation into an exact equation. Construct a differential equation with respect to u to solve for u. (d) Using the ODE with respect to u in part (c), given u(zo) = Ho, when does a unique solution exist? (e) Suppose z = x² + y³. Find u from part (c), if possible. (f) Construct an example of an equation that can be solved using the integrating factor in part (e) and then solve this equation.
