WitrynaThe Newton fractal. The Newton–Raphson method for finding the roots of a function takes an initial guess to a root, x 0, and seeks successively better approximations of it as: x n + 1 = x n − f ( x n) f ′ ( x n). That is, at each iteration, the root is approximated as x n + 1, the x -axis intercept of the tangent to the graph at f ( x n). Witryna9 paź 2024 · 本記事ではPythonでの化学工学計算例を紹介しています。今回はNewton-Raphson法を使用して、対数平均温度差を含む熱収支を計算します。プログラミング系の言語を今まで触ったことがない人をターゲットとし、自分が躓いたところを中心になるべく基礎的なところから解説しています。
