Let y(t) be the solution of y' (t) = f(t, y(t)),t > 0 y(0) = 1 with f(t, y) = cos(t)y. Let At = for T >0 and integer M > 0 and let yn solve = = M vn+1 = vn = f(t, v"), n = 0,1, ..., M = 1 At vo = 1 where t" = nAt. Find a bound (y(t) v1| 0 y(0) = 1 with f(t, y) = cos(t)y. Let At = for T >0 and integer M > 0 and let yn solve = = M vn+1 = vn = f(t, v"), n = 0,1, ..., M = 1 At vo = 1 where t" = nAt. Find a bound (y(t) v1|
