TAILIEUCHUNG - A textbook of Computer Based Numerical and Statiscal Techniques part 59

A textbook of Computer Based Numerical and Statiscal Techniques part 59. 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. | 566 COMPUTER BASED NUMERICAL AND STATISTICAL TECHNIQUES b x1 x1 a b 2 printf f x1 The root of the given equation is . ALGORITHM FOR FALSE POSITION METHOD Step 1. Step 2. Step 3. Step 4. Start of the program to compute the real root of the equation Input the value of x0 x1 and e Check f x0 x f x1 0 If no print Error and exit Step 5. x0f xi - x1f x0 If yes compute x - 2 f x1 - f x0 Step 6. Step 7. Step 8. Step 9. Step 10. Step 11. Step 12. Compute f x2 Again if f x2 x f x0 0 Set x1 - x2 Else set x0 - x2 Continue the process step 5 to step 9 till to get required accuracy Print output End of the program.
