Treated Wood Guide vs Polynomial Solver Step by Step

Learn everything you need to know about how to identify, specify and use preservative treated wood. Explore the preservatives used today that extend the service life of wood from years to decades. Understand the AWPA Use Category system and how it is used to specify and select the proper treated wood products based on its exposure. Review updated information on fire-retardant-treated wood products and see videos on making and using preserved wood products, as well as an overview of the environmental benefits of forests and wood products. For using treated wood in aquatic environments, there are a variety of tools to manage the environmental risks associated with a variety of preservatives, as well as specifying the exclusive Best Management Practices for products using in sensitive environments. Get practical tips and recommendations for all uses of treated wood products and see how these products provide many environmental benefits compared to alternatives such as plastic, steel and concrete. Put everything you need to know about treated wood at your fingertips with the Treated Wood Guide app!

Polynomial Solver Step by Step is a calculator, and, more importantly, a teaching tool. It is designed to help students of both basic and advanced levels. Basic Algebra functions: 1. Polynomial multiplication. 2. Polynomial long division with step by step explanation. 3. Algorithm for finding rational roots consisting of the following: a. Finding all possible rational roots. b. Eliminating the roots outside bounds. c. Performing polynomial long division for each of the roots. d. Adjusting bounds based on long division results if appropriate. Iterative polynomial solving algorithms for advanced-level students: 1. Durand-Kerner method. 2. Aberth method. 3. Newton method with both real and complex starting points. 4. Global (also known as "damped") Newton method with both real and complex starting points. 5. Laguerre method with both real and complex starting points. 6. Bairstow method. 7. Muller method. 8. Eigenvalues of ‘companion matrix’ (demonstration of QR algorithm for eigenvalue calculation is available in our “Matrix Solver Step by Step" app). Interactive graphs are available for: 1. Polynomial functions and their derivatives. 2. Aberth and Durand-Kerner method points on complex plane. 3. Newton, global Newton, Laguerre, and Muller algorithm steps. 4. Newton and global Newton method fractals / convergence images on complex plane 5. Laguerre method convergence images on complex plane 6 Bairstow method convergence images depending on initial approximation values. 7 Muller method convergence images depending on initial approximation values. (Images 4-7 have adjustable settings for area, resolution and shading). Links to online references are included. Please write to us if you like to have new features / chapters added!
