Consider the initial value problem,
f(x,y) = y(18.06  y), y(0) = 12.
The exact solution of the problem increases from y(0) =12 to y = 18.06 as x increases without limit.
Determine the minimum upper bound of h for the classical 4thorder Runge Kutta method to be absolutely stable for this problem. Give your answer to 3 decimal places.
Note : You can make use of table (3.1) of Study Unit 2 Numerical Methods for Differential Equations.
