Interactive calculator for Newton's method, showing tangent-line iterations converging to a root
Newton’s method finds zeroes of a function f(x) by iterating xn+1=xn−f(xn)/f′(xn), using the linearization at each point to produce successively better approximations. This calculator lets you enter a function (with adjustable parameters a,b,c) and visualize the iteration graphically, showing the tangent lines at each step and how the sequence of approximations converges to a zero of f.
