The following three problems illustrate the fact that the super- position principle does not generally hold for nonlinear equa- tions. 17. Show that y = 1/x is a solution of y' + y² = 0, but that if c + 0 and c + 1, then y = c/x is not a solution. 18. Show that y = x³ is a solution of yy" = 6x*, but that if c2 + 1, then y = cx³ is not a solution. 19. Show that yi = 1 and y2 = VA are solutions of yy" + (y')? = 0, but that their sum y = yı + y2 is not a solution.
