Hi, I need answer for the following question:

8. (20 pts) A) State the existence and uniqueness theorem for first order differential equations (Picard's Theorem.) B) What is one big difference, if you are looking at the existence and uniqueness theorem for first order linear differential equations. C) Find the domain (interval of validity) of the solution to the Initial Value Problem (not the solution!) (x2 9):: 3y = sec(x) ,y(2) = 1 D) Find (p0, (p1, (p2, (p3 (Picard Iterates) for the NP: y ' = t + 2y, y(0) = 0
