(35 points) Problem 2: Use the Euler's and classical RK-4 methods to solve the following differential equation: 3xy"-xx+y=0; x(1) = 4, y'(1) = 2 On the interval [1,2] with h = 0.2. (A) [10 points] Solve it to get a true solution using the following substitution method: y = xx (B) [5 points] Cast this DE into an autonomous system of first order differential equations using y1, y2, etc. Provide the IVPS in that form as well.
