Lagrange Interpolation Method
🖋️ Starting from known points Given the task of constructing a function f(x) f(x) f(x)that passes through the points P1(x1,y1),P2(x2,y2),⋯ ,Pn(xn,yn) P_1(x_1, y_1), P_2(x_2, y_2), \cdots, P_n(x_n, y_n) P1(x1,y1),P2(x2,y2),⋯,Pn(xn,yn), first let the projection of the i th point onto the x axis be ...
