Write a program in Python that implements Newton's method to find the roots of a function. The
program must request an initial value. the maximum number of iterations. to tolerance, the function
to which you want to look for the root, and the first derivative of the function.
Verify the operation of your program by finding the root of the function f (x) = cos(x)- with initial
value
Po=7/4 and tolerance of 10*-4
Verify the operation of your program by finding the root of the function f (x) = cos(x)- with initial
value
Po=7/4 and tolerance of 10*-4
Newton's Method To find a solution to f(x)=0 given an initial approximation p0 : INPUT initial
approximation p0; tolerance TOL; maximum number of iterations N0. OUTPUT approximate
solution p or message of failure. Step 1 Set i=1. Step 2 While iN0 do Steps 3-6. Step 3 Set p=p0f(
p0)/f(p0). (Compute pi.) Step 4 If pp0<TOL then OUTPUT ( p); (The procedure was successful.)
STOP. Step 5 Set i=i+1. Step 6 Set p0=p. (Update p0.) Step 7 OUTPUT ('The method failed after
N0 iterations, N0= ', N0 ); (The procedure was unsuccessful.) STOP. Numerical Analysis de
