Persamaan Non – Linier Newton Method Newton’s method atau juga disebut Newton-Raphson adalah skema menentukan solusi numerik dari persamaan f(x) = 0, Metode ini diilustrasikan pada Gambar 1 dibawah. Gambar 1. Ilustrasi dari Newton-Raphson method Mencari solusi dengan memilih nilai untuk titik X1 sebagai estimasi pertama dari solusi persamaan tersebut. Estimasi kedua X2 diperoleh dengan mengambil garis singgung pada titik (X1, f(X1)), diperoleh titik perpotongan dari garis tanget dengan xaksi
