6. Let f(t) be some smooth function: f. f(t) are continuous and bounded. Use the Euler
method with step size k to solve the following ODE
=f(t). 9(0)=0.
The above solution has an exact solution y(t) = f(s)ds. Compare the solutions Job-
tained by the Euler method and improved Euler method with y(t). For fixed t ≤ 1, show
that
yn-y(nk) = n − y(t) → 0
as k→ 0 and n =. You do not need to prove the convergence rate O(k).
Hint: Use integral.
