Code step by step

 

Write a MATLAB code for Newton's method to find solution accurate to within 10 for the following problem. Choose No = 20 and pPo = 0.25.
f (x) = sin x – e=* = 0
f'(x) = cos (x) +e*
ALGORITHM
Newton's
2.3
To find a solution to f(x) =0 given an initial approximation po:
INPUT initial approximation po: tolerance TOL; maximum number of iterations No.
OUTPUT approximate solution p or message of failure.
Step 1 Set i = 1.
Step 2 While i < No do Steps 3-6.
Step 3 Set p = Po - f(Po)/f'(Po). (Compute p.)
Step 4 If |p - Pol < TOL then
OUTPUT (p); (The procedure was successful.)
STOP.
Step 5 Set i =i+1.
Step 6 Set po =p. (Update po.)
Step 7 OUTPUT ('The method failed after No iterations, No =', No):
(The procedure was unsuccessful.)
STOP.
