You can use the following df functions:

Matlab code

% 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, (use different colors!) % Step 3: Label your plot using the command 'legend' % Step 4: Repeat steps 1-3 using with dx=0.1. % % WRITE A COMMENT BELOW: % How accurate was your solution? Do you think making dx smaller will % improve your solution? % a) Define an anonymous function dfl(x,y) = -y % b) Define an anonymous function df2 (x,y) 2*y/x % c) Define an anonymous function df3(x,y) [10* (y (2)-y (1)); % y (1) * (28-y (3))-y (2); y (1) *y (2) -8/3*y (3) ] olo oo % 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.
