Question

Use Euler's method to approximate y(0.7), 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 = 0.7. (Round your answer to

two decimal places.) y(0.7) = ? Then repeat the calculations using two steps with h = 0.35. (Round your answers to two decimal places.) y(0.35) = ? y(0.7) =?

Answer #1

Hope this is fine.

Appreciate feedback.
