A: Approximation of solution to the IVP using Euler's method Professor's Comment: You need the recurrence relation. Plot of Euler's method approximation Plot of the absolute error Professor's Comment: This plot needs to be semilog in the vertical axis. It does not make sense to have it semilog along the horizontal axis. Part 1B: Approximation of solution to the IVP using the Improved Euler's method Professor's Comment : You need the recurrence relation. Plot of Improved Euler's method approximation Plot of absolute error Professor's Comment This plot needs to be semilog in the vertical axis. It does not make sense to have it semilog along the horizontal axis. Part 1C: Approximation of solution to the IVP using the RK4 method Plot of RK4 method approximation Plot of absolute error Professor's Comment: This plot needs to be semilog in the vertical axis. It does not make sense to have it semilog along the horizontal axis. Problem 2 Part 2A: Approximation of the solution to the IVP using the Improved Euler's method Plot for the Improved Euler's method approximation for all 4 time steps Professor's Comment :These graphs are incorrect. Part 2B: Approximation of the solution to the IVP using the RK4 method Plot for the RK4 approximation for all 4 time steps Professor's Comment : These graphs are better. Your discussion is poor
