Consider the initial value problem below to answer to following. a) Find the approximations to y(0.4) and y(0.8) using Euler's method with time steps of At = 0.4, 0.2, 0.1, and 0.05. b) Using the exact solution given, compute the errors in the Euler approximations at t= 0.4 and t= 0.8. c) Which time step results in the more accurate approximation? Explain your observations. d) In general, how does halving the time step affect the error at t = 0.4 and t= 0.8? y'(t) = 6t + 1, y(0) = 0, y(t) = 3r² +t
