Alstonargodi/Newton-Rapshon-Calc

Newton Raphson calculator to find function root - p

MetodeNewton-Raphson

is a method of finding the root of a function f(x) with a one-point approach, where the function f(x) has a derivative. This method uses a one-point approach as a starting point. The closer our chosen starting point is to the real root, the faster it will converge to the root. more information about newtonrapshon

algorithm

1. Start
2. Define the function as f(x)
3. Define the first derivative of f (x) g (x) g (x) i (x)
4. Enter the first number, coefficient x, constant, initial estimate (top), tolerable error (error) and maximum iterations (bottom)
5. Initialization of iteration counter i = 1
6. If g (top) = 0 then print "Error" and go (12) otherwise go (7)
7. Calcualte x1 = up - f (above) / add (above) for addition and calcualte x1 = up - f(above)/less(above) for subtraction
8. Iteration counter increment i = i + 1
9. If i>=N then print "not convergent" and go (12) otherwise go (10)
10. If | f(x1) | > e then set up = x1 and go (6) otherwise go (11)
11. Print the result as x1
12. Stop

pseudocode

1. Start
2. Define the function as f(x)
3. Define the derivative of the function as g(x)
4. Input: A. Initial guess over b. Error Tolerable error c. Bottom Maximum Iteration
5. Initialization of iteration counter step = 1
6. Do it

If bottom(up) = 0
Print "error"
Stop
Ends if
if operator +
x1 = up - f (up)/plus(up)
  top = x1
if operator -
x1 = up - h(up)/less(up)

step = step + 1

If step> down
Print "Not Converging"
Stop
Ends if
   While abs f(x1)> e

7. Print root as x1
8. Stop """
