2. Consider the following first-order ODE:
=x-y
from x = 0 to x = 1.2 with y(0) = 1
(a) Solve by hand with Euler's explicit method using h = 0.4.
(b) Solve by hand with the modified Euler method using h = 0.4-
(c) Solve by hand with the classical fourth-order Runge-Kutta method using h = 0.4.
The analytical solution of the ODE is: y=x+2e-1. In each part, calculate the error between the true
solution and the numerical solution at the points where the numerical solution is determined.
