Use the Extrapolation Algorithm with TOL 10~4 to approximate the solutions to the following initial-value problems: a. y' (y/t)2 + y/t, I < t < 1-2, y(l) = 1, with hmax 0.05 and hmin 0.02. b. y' = sin r + e - ', 0 < r < 1, y(0) = 0, with hmax = 0.25 and hmin = 0.02. c. y' = (y2 + y)/t, 1 < r < 3, y(0) = 2, with hmax = 0.5 and hmin = 0.02. d. y' t 2 , 0 < r < 2, y(0) = 0, with hmax 0.5 and hmin 0.02.
