"Numerical Analysis" by is considered a top choice for students due to several factors:

Based on the Intermediate Value Theorem, this method involves repeatedly bisecting an interval $[a, b]$ where $f(a)$ and $f(b)$ have opposite signs. The root is bracketed within smaller and smaller intervals.

Solving a system of linear equations $Ax = b$ is ubiquitous in engineering.

The book "Numerical Analysis" by Dutta Jana is a comprehensive textbook that covers the fundamental concepts and techniques of numerical analysis. The book is designed for undergraduate and graduate students, as well as professionals who need to learn numerical analysis. The book covers a wide range of topics, including:

A completely free, collaborative online textbook covering everything from root-finding to differential equations.

Solving Initial Value Problems (IVPs) using Euler’s method and the Runge-Kutta (RK) 4th order method. How to Use This Resource Effectively

Before diving into calculations, the text explains the types of errors (truncation and round-off) that occur in numerical computation, laying the groundwork for understanding the accuracy of methods.

The first step in any successful search is knowing exactly what you are looking for. The keyword "free pdf on numerical analysis by dutta jana top" is very specific, but it points to a minor, common confusion in the author's name.

Solve a problem manually using the Dutta & Jana steps first. Then, try to write a small script to solve the same problem. This bridges the gap between mathematics and computer science.

The raw difference between the true and approximate value. Relative error: The error scaled against the true value.

It provides a vast repository of worked-out examples that help readers understand the application of formulas.

This is the safest and most reliable route. The book is listed in several online library catalogs. While you may not be able to download a PDF directly, you can often find which physical libraries own a copy. For instance, the lists the book. If you are a student, your own university or department library is the very first place you should check, both for a physical copy and to see if they have an institutional subscription to an e-book version.

Understanding absolute, relative, and percentage errors, and how they propagate through calculations.
