The Euler method is a numerical method for EDO resolution based on Taylor expansion like gradient descent algorithm . Witryna15 maj 2024 · 1 Answer. Sorted by: 5. Expanding the comment of Winther: Yes, but write y ″ = u ′ 2 to get the first order system: u ′ 1 = u2 and u ′ 2 = u1 + u2 + t. Now apply Euler's method one step: In the next step you would get y(2h) = u1(2h) ≈ u1(h) + hu2(h) ≈ 1 + h ⋅ h and y ′ (2h) = u2(2h) ≈ u2(h) + h [u1(h) + u2(h) + h] ≈ h + h ...
