: Newton’s forward/backward formulas and Lagrange interpolation. Linear Systems : Gaussian elimination and LU decomposition.
The simplest one-step method. It uses the tangent line to approximate the curve. $$y_n+1 = y_n + h f(x_n, y_n)
They break down complex iterative methods into step-by-step logic suitable for programming.
