Okay guys i need help with this part of my code. the first image is what i need to do. says i need to compute numerical solution error at t=0.5 with each timestep. I am posting what i have for the first one so far. Is this correct? Or am i doing this wrong. Below is my code so far.

% compute numerical solution error at t-0.5 for forward Euler with 5 % time steps. % Compute numerical solution error at t,:0.5 for forward Euler with 50 % time steps. % Compute numerical solution error at t,:0.5 for forward Euler with 500 % time steps
