Math Problem Statement
False Position Method The following equations has a root in the indicated interval. Using False Position Method, generate the first four elements in the sequence that eventually converges to the root 2e^−x/2 + ln x = 1, (0.1,1)
Solution
The False Position Method (also called the Regula Falsi method) is a numerical method used to solve equations of the form , where is a continuous function. It iteratively refines the estimate of the root based on the values of at two points that bracket the root.
Given equation:
We need to rewrite this equation in the form:
We are also given the interval , which means the root lies between these two values. Let's now apply the False Position Method to generate the first four approximations of the root.
Step 1: Calculate at the endpoints of the interval
We first evaluate the function at the endpoints and .
1. Evaluate :
2. Evaluate :
Step 2: Calculate the first approximation using the False Position formula:
The False Position formula for the next approximation is: [ x_2 =
