Numerical analysis is the branch of mathematics that studies the design and implementation of algorithms for solving numerical problems. Numerical analysis is essential for many applications in science, engineering, and computer science, such as finding roots of equations, solving systems of linear equations, interpolating and approximating functions, integrating and differentiating functions, solving ordinary and partial differential equations, and optimizing functions.

There are many textbooks that cover the theory and practice of numerical analysis, but one of the most popular and comprehensive ones is Numerical Analysis by Richard L. Burden, J. Douglas Faires, and Annette M. Burden. The 10th edition of this book was published in 2016 by Cengage Learning, and it contains 29 chapters that cover a wide range of topics in numerical analysis, such as error analysis, root-finding methods, matrix algebra, direct and iterative methods for linear systems, interpolation and polynomial approximation, numerical differentiation and integration, initial-value problems for ordinary differential equations, boundary-value problems for ordinary differential equations, finite difference methods for partial differential equations, optimization methods, and Fourier analysis.

The 10th edition of Numerical Analysis also includes many features that enhance the learning experience of students and instructors, such as:

More than 2500 exercises that range from elementary applications to generalizations and extensions of the theory.

Many examples that illustrate the concepts and algorithms discussed in the text.

Historical notes that provide background information on the development of numerical analysis and its pioneers.

Projects that allow students to explore topics in more depth and apply numerical methods to real-world problems.

Matlab code files that can be downloaded from the companion website for the student examples and algorithms. The code files require the Symbolic Math Toolbox to run.

## Error Analysis

One of the first topics that is discussed in Numerical Analysis 10th Edition is error analysis. Error analysis is the study of the sources, types, and effects of errors that arise in numerical computations. Errors can be classified into two main categories: round-off errors and truncation errors.

Round-off errors are caused by the finite precision of the arithmetic operations performed by computers. For example, if we try to represent the irrational number $\pi$ using a finite number of decimal digits, we will inevitably lose some accuracy and introduce some error. Round-off errors can propagate and accumulate throughout a computation, affecting the final result.

Truncation errors are caused by the approximation of mathematical processes that are infinite or continuous by finite or discrete ones. For example, if we try to approximate a function by a polynomial, we will inevitably introduce some error due to the difference between the function and the polynomial. Truncation errors can be reduced by increasing the number of terms or points used in the approximation, but this may also increase the computational cost and complexity.

To measure and control the errors in numerical computations, we need to use some tools and techniques, such as:

Absolute error and relative error, which quantify the difference between an approximate value and an exact value.

Significant digits, which indicate the number of digits in an approximate value that are reliable.

Floating-point arithmetic, which is a system for representing and manipulating real numbers using a fixed number of bits.

Error propagation, which analyzes how errors affect the results of arithmetic operations and functions.

Error estimation, which provides bounds or intervals for the true value of a quantity based on its approximate value and its error.

Error reduction, which applies methods or algorithms that minimize or eliminate errors in numerical computations.

Example: Suppose we want to compute the area of a circle with radius $r=1.5$ using the formula $A=\pi r^2$. If we use $\pi=3.14$ as an approximation, what is the absolute error, relative error, and number of significant digits in our result?

Solution: The exact value of $\pi$ is approximately $3.14159265...$. Therefore, using $\pi=3.14$ introduces a round-off error of $0.00159265...$. The exact value of $A$ is approximately $7.06858347...$. Therefore, using $A=3.14\times 1.5^2=7.065$ introduces a truncation error of $0.00358347...$. The absolute error in our result is $7.065-7.06858347...=0.00358347...$. The relative error in our result is $\frac7.06858347...=0.00050715...$. The number of significant digits in our result is 4, since the first four digits (7.06) are correct.

## Root-Finding Methods

Another important topic that is covered in Numerical Analysis 10th Edition is root-finding methods. Root-finding methods are algorithms for finding solutions of equations of the form $f(x)=0$, where $f$ is a given function. Finding roots of equations is a common problem in many applications, such as physics, chemistry, engineering, economics, and biology.

There are many root-finding methods that can be used for different types of equations and functions, such as:

Bisection method, which divides an interval containing a root into two subintervals and repeats until a desired accuracy is achieved.

Fixed-point iteration method, which transforms an equation into an equivalent one of the form $x=g(x)$ and iterates until a fixed point (a root) is reached.

Newton's method, which uses the tangent line of the function at a point to approximate the root and iterates until convergence.

Secant method, which uses the secant line of the function through two points to approximate the root and iterates until convergence.

False position method, which uses the secant line of the function through two points that bracket a root to approximate the root and iterates until convergence.

Example: Suppose we want to find a root of the equation $f(x)=x^3-2x-5=0$ using Newton's method. If we start with an initial guess of $x_0=2$, what are the next two iterations of Newton's method?

Solution: Newton's method uses the formula $x_n+1=x_n-\fracf(x_n)f'(x_n)$ to generate a sequence of approximations to the root. The derivative of $f$ is $f'(x)=3x^2-2$. Therefore, using $x_0=2$, we get:

$x_1=2-\fracf(2)f'(2)=2-\frac(2)^3-2(2)-53(2)^2-2=2-\frac110=1.9$

$x_2=1.9-\fracf(1.9)f'(1.9)=1.9-\frac(1.9)^3-2(1.9)-53(1.9)^2-2=1.9-\frac-0.082710.23=1.908$ Here is the continuation of the article that I wrote for the keyword "numerical analysis 10th edition pdf download". $\det(A)$$0$
