TAILIEUCHUNG - A textbook of Computer Based Numerical and Statiscal Techniques part 60

A textbook of Computer Based Numerical and Statiscal Techniques part 60. By joining statistical analysis with computer-based numerical methods, this book bridges the gap between theory and practice with software-based examples, flow charts, and applications. Designed for engineering students as well as practicing engineers and scientists, the book has numerous examples with in-text solutions. | 576 COMPUTER BASED NUMERICAL AND STATISTICAL TECHNIQUES Step 10.
