Hello! I've been debugging this VBA program that computes the root of an equation using Newton Raphson method and with the use of the UserForm. The user will type the equation, the initial guess and the number of iterations. I was able to search on automatically differentiating the equation unlike when the user still has to type in the derivation of the equation. The next problem I encountered was the exponential function. I would like the program to evaluate the equation whether it is simple polynomial or exponential function. I'd like my program to be flexible in either of the … +0 Code Snippet Newton's Method Example (Python) A Python code example to find an approximate value for x in f(x) = 0 using Newton's method. +2 Hi everyone, this is my first post and I am new to C++. I am trying to figure out how to do this project. Newton’s method is an algorithm that can be used to solve an equation of the form f(x) = 0 using a sequence of approximations. Here’s how it works: You make a reasonable guess for a solution, x0. You should create a function which calculates the value of the polynomial at a specific x value (the inputs for the function should be the array representing the polynomial, its size, and the x-value to evaluate at), and a … +0 Newton's Method to find polynomial solution Hi everyone, this is my first post and I am new to C++.

Below is the algorithm implementation in C: #include #include #include int main() { double guess,newguess,input,error=1.0; printf("Enter the input number"); scanf("%f",&input); printf("Enter the guess for the reciprocal of the input number between -1.0 and 1.0"); scanf("%f",&guess); while(error>0.0001) { newguess=guess*(2-(input*guess)); error=newguess-guess; guess=newguess; } printf("The reciprocal of the input number is %f",newguess); system("pause"); return 0; } When I enter 3 as my input number, i get an absurd answer. On using hand-calculations on paper, I am converging to the right value of … +0 Code Snippet Newton-Raphson in C# I find C# very well suited for doing math and all sorts of calculations, so here is an example. Just start a Console application and fill in the code. Have fun! The code also shows a use of delegates and some Console functions. If you don't know what the Newton-Raphson iteration method is, you can look it up [url=http://en.wikipedia.org/wiki/Newton%27s_method]here[/url] There is much to be improved in my code: Could have asked the user for input, instead of hardcoding some values. Could have made a Forms app out of it. Etc. +0

The End.
