MY NOTES ASK YOUR TEACHER Use Euler's method to approximate y(0.9), where y(x) is the solution of the initial-value problem y" - (2x + 1)y = 1, y(0) = 3, y'(0) = 1. First use one step with h = 0.9. (Round your answer to two decimal places.) y(0.9) = 3.90 Then repeat the calculations using two steps with h = 0.45. (Round your answers to two decimal places.) y(0.45) = 3.45 y(0.9) = 4,71 X Need Help? Read It Talk to a Tutor
