For each choice of f (t, y) given in parts (a)-(d): i. Does f satisfy a Lipschitz condition on D = {(t, y) | 0 ≤ t ≤ 1, −∞ < y < ∞}? ii. Can Theorem 5.6 be used to show that the initial-value problem y = f (t, y), 0≤ t ≤ 1, y(0) = 1, is well-posed? a. f (t, y) = et−y b. f (t, y) = (1 + y)/(1 + t) c. f (t, y) = cos(yt) d. f (t, y) = y2/(1 + t)
