h
15. Let E(h)
a. For the initial-value problem
y/ = -y+1, 0<t< 1, y(0) = 0,
compute the value of h to minimize E(h). Assume 8 = 5 × 10–(2+1) if you will be using n-digit arithmetic in part (c).
ANSWER Į
b. For the optimal h computed in part (a), use Eq.- (5.13) to compute the minimal error obtainable.
ANSWER Į
c. Compare the actual error obtained using h = 0.1 and h = 0.01 to the minimal error in part (b). Can you explain the results?
