1. Write a Matlab function called RK2 that solve (1) using Order 2 Runge-Kutta method. Use this method to solve the IVP (2) with N- 20,50, 100. Call y0, y1, y2, the three results and plot the three solutions on the same graph. Make a loglog plot of absolute error at t 1 versus the number of intervals for all three methods on the same plot. Compare the solution at t - 1 with the exact solution att Create Err a vector that stores the absolute error of the three solutions at t - 1. Comment on the result (is the method converging or not, etc.) using %
