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.
Use false position method to find the root of ?(?) = −sin(? − 5)
+ ? with initial guesses of 0.2 and 1. Show up to three iterations
and calculate the relative percent error ?? for each iteration
possible? Show full details for at least one iteration to get full
points. Also, if three significant figure accuracy is required,
show if the value after third iteration is acceptable or not.
1. Locate a root of sin(x)=x2 where x is in radians.
Use a graphical technique and bisection with
the initial interval from 0.5 to 1. Perform the computation until
ea is less than es=2%. Also
perform an error check by substituting your final answer into the
original equation.
2. Determine the positive real root of ln(x
2
)=0.7 using three iterations of the bisection method,
with initial interval of [0.5:2].
3. Determine the lowest positive root of f(x)=7sin(x)e
-x
-1...
Estimate a real root of the polynomial
f(x) = 5x4-2x3-25x2-6x+45 between
x=1 and x=2 (using bisection, Standard Newton-Raphson, Secant, and
modified Newton-Raphson, and modified Secant methods). Show the
detailed calculations for 5 iterations (for each method)
f(x)=x^3-3x-1=0
x=[0,2]
epsilon=5*10^-2
1. perform the bisection method for the root in [0,2] until your
root is closer to the real root within epsilon.
Let x_0=1.0, x_1=1.2
2. perform the secant method until your root is closer to the
real root within epsilon.
3. do as in 2. with the Newton's method, with x_0=1.1
a) you can see a program for using bisection search to find the
square root of x:
x = 25
epsilon = 0.01
low = 0.0
high = max(1.0, x)
guess = (low + high) / 2
numberofguesses = 1
while abs(guess ** 2 - x) > epsilon :
print('low =', low, 'high = ', high, 'guess = ', guess)
if guess** 2 > x : # the guess is too high, so move high down
to guess
high =...
To find a positive root for , write a MATLAB script file that
uses Bisection method. Choose any initial value that is needed. Use
absolute relative approximate error to be less than 0.01. Your code
should report the number of iteration and the value of x.
