7. Finding Roots Using the Bisection Method
Write a function that implements the "bisection method" for
finding the roots of function. The signature of your function
should look like
def find_root(f,a,b,n):
where n is the maximum number of iterations of to search for the
root.
The code should follow this algorithm:
We are given a continuous function f and numbers a and b and
with a<b with f(a)<0<f(b). From the intermediate value
theorem we know that there exists a c...
I am asked to find the square roots using the bisection method
for x * x - a = 0.
I was wondering how the bisection method is performed.
Let's suppose a = 9, so I would need to find the roots of x * x
- 9 = 0.
Also, from the 1st equation, when would the bisection method NOT
output a root?
Using the bisection method:
Make a program to use this method using the
following three functions and use it to find the root of this
function f (x) = x * x * x-8.
a) A function so that the user between xlower and xupper that meets
the value of the function has a different sign and if he does not
ask for new values.
b) A function to find the root and call it bisection and perform a...
Using the bisection method, find the root of the following
function:
f(x)=cos(2x) - x
Use the following initial values: xl=0 and xu=2
NOTE: Perform only 3 iterations.
USING BISECTION METHOD, FIND THE ROOT OF 0.5e^x - 5x + 2 = 0 ON
THE INTERVAL [ 0 , 1 ] UP TO 3 DECIMAL PLACES.
USE NEWTON'S METHOD TO APPROXIMATE THE ROOT OF f(x)=x^2-5
IN THE INTERVAL [ 2 , 3 ] UP TO 4 DECIMAL
PLACES.
Implement in MATLAB the Newton-Raphson method to find the roots
of the following functions.
(a) f(x) = x 3 + 3x 2 – 5x + 2
(b) f(x) = x2 – exp(0.5x)
Define these functions and their derivatives using the @ symbol.
For example, the function of part (a) should be f=@(x)x^3 + 3*x.^2
- 5*x + 2, and its derivative should be f_prime=@(x)3*x.^2 + 6*x -
5.
For each function, use three initial values for x (choose
between -10...

Find the data for the problem in the first worksheet named
LightbulbLife of the data table down below It gives the data on the
lifetime in hours of a sample of 50 lightbulbs. The company
manufacturing these bulbs wants to know whether it can claim that
its lightbulbs typically last more than 1000 burning hours. So it
did a study.

# Problem Description
Given a directed graph G = (V, E), find the number of
connected components in G.
# Input
The graph has `n` vertices and `m` edges.
There are m + 1 lines, the first line gives two numbers `n`
and `m`, describing the number of vertices and edges. Each of the
following lines contains two numbers `a` and `b` meaning there is
an edge (a,b) belong to E. All the numbers in a line...
