Use the improved Euler method to find the approximate values of the solution for the given initial value problem at x = 0.5, and 2. Use the step sizes (h) as 0.1 and 0.05 for each equation. a) dy = 5x - 3 y, y(0) =2 dx dy b) =2xte, y(0) =1 dx (Note 2: Use the "improved. euler.m" file to solve the problem and follow the directions given at the end of the file. The "improved.euler.m" file is in the MATLAB Project folder on the Blackboard.)
