In MATLAB: ------------------------------------------------------------------------ WRITE CODE BELOW: Step 1: Write code to solve the ODE given by f'(x)+f(x)=0 on the interval [0,5] with the initial condition f(0)=1. Use Euler's Method with dx=0.5. Step 2: The exact solution is e^(-x). Plot e^(-x) and the solution you obtained on the same plot Step 3: Label your plot using the command 'legend' Step 4: Repeat steps 1-3 using with dx=0.1. ------------------------------------------------------------------------
