https://amser.org//index.php?P=FullRecord&ResourceId=14321
https://amser.org//index.php?P=FullRecord&ResourceId=14321In this activity students view and analyze images of ramps and steps to see if they conform to the requirements of the Americans with Disabilities Act. Students measure horizontal and vertical distances and compute the percent slope for each image. Image measurements are performed using WebImage, a Web-based, customized version of ImageJ.Mon, 26 Jul 2010 03:00:02 -0500Slope Fields
https://amser.org//index.php?P=FullRecord&ResourceId=13751
https://amser.org//index.php?P=FullRecord&ResourceId=13751Created by David Smith for the Connected Curriculum Project, this module develops a graphical representation for a differential equation that reveals the nature of solutions, even when formulas for those solutions are not available. This is one within a much larger set of learning modules hosted by Duke University.Fri, 4 Jun 2010 03:00:02 -0500Application of the Finite Element Method to Slope Stability
https://amser.org//index.php?P=FullRecord&ResourceId=7495
https://amser.org//index.php?P=FullRecord&ResourceId=7495This document outlines the capabilities of the finite element method in the analysis of slope stability problems. A description of the constitutive laws of material behavior such as the Mohr-Coulomb failure criterion, and material properties input parameters, required to adequately model slope failure is given as well.Tue, 23 Sep 2008 20:51:53 -0500Dave's Short Trig Course

Contents include applications of trigonometry, angle measurement, chords, sines, cosines, tangents and slope, the trigonometry of right triangles, the trigonometric functions and their inverses, oblique triangles, and a summary of trigonometric identities.Mon, 22 Sep 2008 03:00:02 -0500SIMULATION OF SLOPE FAILURE USING A MESHED BASEDPARTITION OF UNITY METHOD
https://amser.org//index.php?P=FullRecord&ResourceId=7507
https://amser.org//index.php?P=FullRecord&ResourceId=7507A mesh based partition of unity method, known as the manifold method, is used in simulating the evolution of a slope failure. The problem configuration consists of a simple slope that has pre-existing tensile cracks along its crest. The slope failure is triggered by rainfall which raises water pressure in the crack. As the tensile stress around the crack tip increases, an existing crack grows and a failure surface is eventually developed. The maximum stress criterion is adopted in determining the crack growth and growth direction. After a failure surface is formed, the unstable soil mass, bounded by the failure surface, slides down the slope. This sliding process is also modeled.Mon, 25 Aug 2008 03:00:07 -0500Derivatives

https://amser.org//index.php?P=FullRecord&ResourceId=6552Murray Bourne developed the Interactive Mathematics site while working as a mathematics lecturer at Ngee Ann Polytechnic in Singapore. The site contains numerous mathematics tutorials and resources for students and teachers alike. This specific page is focused on differentiation, or finding derivatives. Bourne walks users through an introduction to differentiation and limits, and then moves on to more specific applications like rate of change, derivatives of polynomials, and differentiating powers of a function. Each topic includes graphs and interactive materials designed to aid users in understanding the presented concepts. The information here is presented in a clear, straightforward manner that is appropriate for introductory and advanced calculus students alike.Tue, 22 Apr 2008 03:00:03 -0500College Algebra Online Tutorials

https://amser.org//index.php?P=FullRecord&ResourceId=5545The introduction to this site remarks, "If you need help in college algebra, you have come to the right place." Their statement is accurate, as the staff members at the West Texas A&M University's Virtual Math Lab have done a fine job creating a series of online algebra tutorials for students and anyone else who might be returning to the world of algebra. First-time visitors should look at their online guide to the tutorials to learn how their tutorials are organized. After that, they should feel free to browse through any of the 59 tutorials offered here. Each tutorial contains information about learning objectives, full explanations, and numerous examples of how to correctly solve problems.Mon, 10 Dec 2007 03:00:01 -0600Practical Algebra Lessons
