Experiment 13: Roots Finding of Nonlinear Equations (Newton Raphson and Bisection
methods)
1. Using Newton Raphson method
Find the smallest positive zero of:
f(x) = x* – 6.4x³ + 6.45x2 + 20.538x – 31.752
Near to x = 2
2.
Use MATLAB to sketch the graph y f(x) for each of the following functions, and verify
from the graph that f(a) and f(b), where a and b defined below, have opposite signs. Then,
use Newton's method to estimate the root of f(x) = 0 that lies between a and b.
a. f,(x) = x'+x- 3
a = 1
b = 2
b. f,(x) = /2x +1-x+ 4
a = 2
b = 4
Hint: Start with x, (a+b)/2
3.
Find the zero of fix)=x-tan(x) in the interval (4,20) by the method of bisection Using Matlab
codes.
Using both Newton Raphson and Bisection methods
4.
A root of f(x) = x - 10x? + 5 = 0 lies close to x-0.7. Compute this root with the Newton-
Raphson method.
