Example 5.  Solve the I.V.P.   [Graphics:Images/RungeKuttaMod_gr_66.gif]  over  [Graphics:Images/RungeKuttaMod_gr_67.gif].  Use the Runge-Kutta method with  100  subintervals of  [0, 10]  to get a numerical approximation to the solution.  Plot the solution using the 101 points you just computed in the window {{0,10},{0,1}}.  Report the last point which is the numerical approximation to  (10, y(10)).
Solution 5.
