Finding roots of functions
WebFeb 14, 2013 · I found out it's relatively easy to implement your own root finder using the scipy.optimize.fsolve. Idea: Find any zeroes from interval (start, stop) and stepsize step by calling the fsolve repeatedly with changing x0. Use relatively small stepsize to find all the roots. Can only search for zeroes in one dimension (other dimensions must be fixed). WebSep 7, 2024 · Newton’s method makes use of the following idea to approximate the solutions of f ( x) = 0. By sketching a graph of f, we can estimate a root of f ( x) = 0. Let’s call this estimate x 0. We then draw the tangent line to f at x 0. If f ′ ( x 0) ≠ 0, this tangent line intersects the x -axis at some point ( x 1, 0).
