Consider the following IVP
y′ = 2t − y + 1, y(0) = 1.
Find an approximation of y(1) using
(a) the Euler’s method with N = 4,
(b) the Euler’s method with N = 8,
(c) the improved Euler’s method with N = 4,
(d) the improved Euler’s method with N = 8.
Solve the IVP, find y(1), and compare the accuracy |y(1)−yN | of
the approximations.
