By show it means prove not solve for the if again
Thank you!

consider the Riccati equation y'=p(x)+q(x)y+r(x)y^2. If a particular solution y1(x), show that the general solution y(x) has the from y(x)=y1(x)+z(x); where z(x) is the solution of the bernoulli equation: z'-(q+zry1)z=rz^2 Use this technique to find the general solution of the equation, y'=y/x+x^3y^2-x^5. (Hint: Verify that y1(x)=x is a particular solution)
2. a. Show that y² + x – 3 = 0 is an implicit solution to dy/dx = -1/(2y) on the interval (-0, 3). b. Show that xy3 – xy: sin x = 1 is an implicit solution to dy_(x cos x + sin x - 1) y 3(x - x sin x) on the interval (0, /2).
2) Show that a Green's function G(x,y) satisfying the problem a2G = 8(x - y), G (0,y) = 6,(1, y) = 0 does not exist, but a modified Green's function Ĝ(x,y) satisfying a2G 22 = (x - y) -1, G.(0,y)=G.(1,y) = 0 does. How would you use G to solve problem (1) when f satisfies the condition that you found for a solution to exist? Hint: is f(x) = f(u) (8(x - y) - 1) dy?
