Find the solution of the system x' = 4y, y'= -2x, where primes indicate derivatives with respect to t, that satisfies the initial condition (0) = 4, y(0) = 1. X = y = Based on the general solution from which you obtained your particular solution, complete the following two statements: The critical point (0,0) is A. unstable OB. stable C. asymptotically stable and is a A. saddle point B. node O C. spiral D. center
