Munthe-Kaas a,3 a Department of Informatics, University of Bergen, N-5020 Bergen, Norway b Department of Mathematical Sciences, NTNU, N-7491 Trondheim, Norway Abstract We describe an object-oriented MATLAB toolbox for solving differential equations on manifolds. The software reflects recent development within the area of geometric integration. Through the use of elements from differential geometry, in particular Lie groups and homogeneous spaces, coordinate free formulations of numerical integrators are developed. The strict mathematical definitions and results are well suited for implementation in an object- oriented language, and, due to its simplicity, the authors have chosen MATLAB as the working environment. The basic ideas of DiffMan are presented, along with particular examples that illustrate the working of and the theory behind the software package. 2001 IMACS. Published by Elsevier Science B.V.

Introduction DiffMan is an object-oriented MATLAB [24] toolbox designed to solve differential equations evolving on manifolds. The current version of the toolbox addresses primarily the solution of ordinary differential equations. The solution techniques implemented fall into the category of geometric integrators— a very active area of research during the last few years. The essence of geometric integration is to construct numerical methods that respect underlying constraints, for instance, the configuration space * Corresponding author.

  • Step-By-Step Solution Possibilities in Different Computer Algebra Systems
    Step-by-Step Solution Possibilities in Different Computer Algebra Systems Eno Tõnisson University of Tartu Estonia E-mail: [email protected] Introduction The aim of my research is to compare different computer algebra systems, and specifically to find out how the students could solve problems step-by-step using different computer algebra systems. The present paper provides the preliminary comparison of some aspects related to step-by-step solution in DERIVE, Maple, Mathematica, and MuPAD. The paper begins with examples of one-step solutions of equations. This is followed by a cursory survey of useful commands, entering commands, programming etc. I hope that a more detailed and complete review will be composed quite soon. Suggestions for complementing the comparison are welcome. It is necessary to know which concrete versions are under consideration. In alphabetical order: DERIVE for Windows. Version 4.11 (1996) Maple V Release 5. Student Version 5.00 (1998) Mathematica for Students. Version 3.0 (1996) MuPAD Light. Version 1.4.1 (1998) Only pure systems (without additional packages, etc.) are under consideration. I believe that there may be more (especially interface-sensitive) possibilities in MuPAD Pro than in MuPAD Light. My paper is not the first comparison, of course. I found several previous ones in the Internet. For example, 1. Michael Wester. A review of CAS mathematical capabilities. 1995 There are 131 short problems covering a broad range of symbolic mathematics. http://math.unm.edu/~wester/cas/Paper.ps (One of the profoundest comparisons is probably M.

A method of us- ing rules to manipulate mathematical expressions in small steps is suggested and implemented. The problem of creat- ing a step-by-step solution by choosing which rule to apply and when to do it is redefined as a graph search problem and variations of the A* algorithm are used to solve it. It is all put together into one prototype solver that was evalu- ated in a study. The study was a questionnaire distributed among high school students. The results showed that while the solutions were not as good as human-made ones, they were competent. Further improvements of the method are suggested that would probably lead to better solutions.

  • Analytic Geometry
    CHAPTER 2 Analytic Geometry Euclid talks about geometry in Elements as if there is only one geometry. Today, some people think of there being several, and others think of there being infinitely many. Hopefully, after you get through this course, you will be in the second group. The people in the first group generally think of geometry as running from Euclid to Hilbert and then branching into Euclidean geometry, hyperbolic geometry and elliptic geometry. People in the second group understand that perfectly well, but include another, earlier brach starting with Rene Descartes (usually pronounced like “day KART”). This branch continues through people like Gauss and Riemann, and even people like Albert Einstein. In my mind, two of the major advances in the understanding of geometry were known to Descartes. One of these, was only known to Descartes, but Gauss, it seems, figured it out on his own, and we all followed him. The other you know very well, but you probably don’t know much about where it came from. This was the development of analytic geometry, geometry using coordinates. The other is not known very well at all, but Descartes noticed something that tells us that geometry should be built upon a general concept of curvature. What is generally called Modern geometry begins with Euclid and ends with Hilbert. The alternate path, the truly contemporary geometry, begins with Descartes and blossoms with Riemann. Note that, as is typical, modern usually means a long time ago. We’ll look at analytic geometry first, and Descartes’ other piece of insight will come later.

  • Week 4: Differential Equations & Linear Algebra Notes
    Christian Parkinson GRE Prep: Diff. Eq. & Lin. Alg. Notes 1 Week 4: Differential Equations & Linear Algebra Notes After calculus, the most common topic on the math subject GRE is linear algebra, foll- wed by differential equations. Since the latter is a more natural continuation of calculus (and since it will take much less time), I cover it first. Differential Equations Definition 1 (Differential Equation). An ordinary differential equation is an equation of the form F (x; y; y0; y00; : : : ; y(n)) = 0 for some function F : Rn+2 ! R where y(k) denotes the kth derivative of y with respect to the independent variable x. The order of the differential equation is equal to the highest order derivative of u which appears; the above equation is nth order (assuming F does actually depend on its last variable). Note, we often replace y with u which can be thought to stand for \unknown." The goal then, is to find the unknown function which satisfies the equation. On the math subject GRE, questions are mostly limited to equations where the highest order derivative of the unknown function can be isolated; that is, equations of the form y(n) = f(x; y0; : : : ; y(n−1)): Many differential equations can be solved by simply recalling facts from calculus. Example 2. Solve the differential equations (a) u0 = u; (b) y00 = −4y: Solution. For (a), we can phrase the differential equation as a question: \What function will remain the same upon differentiating?" We recall from calculus that u(x) = ex is the function which is invariant under differentiation.

  • Elementary Algebra Review
    Placement Test Review Materials for 1 To The Student This workbook will provide a review of some of the skills tested on the COMPASS placement test. Skills covered in this workbook will be used on the Algebra section of the placement test. This workbook is a review and is not intended to provide detailed instruction. There may be skills reviewed that you will not completely understand. Just like there will be math problems on the placement tests you may not know how to do. Remember, the purpose of this review is to allow you to “brush-up” on some of the math skills you have learned previously. The purpose is not to teach new skills, to teach the COMPASS placement test or to allow you to skip basic classes that you really need. The Algebra test will assess you r mastery of operations using signed numbers and evaluating numerical and algebraic expressions. This test will also assess your knowledge of equations solving skills used to solve 1-variable equations and inequalities, solve verbal problems, apply formulas, solve a formula fro a particular variable, and fined “k” before you find the answer. You will also be tested on your knowledge of exponents, scientific notation, and radical expressions, as well as operations on polynomials. Furthermore, other elementary algebra skills that will be on the test include factoring polynomials, and using factoring to solve quadratic equations and simplify, multiply, and divide rational expressions. 2 Table of Contents Evaluating Expressions Using Order of Operations 4 Simplifying Complex Fractions

  • Higher-Order Linear Differential Equations
    Higher-Order Linear Differential Equations Sean Z. Roberson March 29, 2014 In Chapter 2, we examined a linear differential equation of the form y0 + P y = Q, where P and Q were functions of x (or whatever independent variable is used in the context of the problem). The solution was simple to construct by using an integrating factor. In Chapter 4, our focus shifted to higher-order linear differential equations (which I will abbreviate as DE from now on) which took a bit more work to solve. This paper will summarize the methods discussed in this chapter and will show how to apply each method. 1 Reduction of Order To begin, let's say that one (fundamental) solution of a differential equation is given. How can you find the rest? Doing so requires a substitution. In order to find a second solution to a second-order linear DE, assume that this second solution y2 is the product of some unknown function u and the known solution y1. With this assumption, we take derivatives (quite unfortunately, using the product rule multiple times) and substitute into the DE. Afterwards, the equation is now in terms of the unknown function u, but solely in its derivatives. The equation can then be solved by making the substitution w = u0, which reduces into a first-order DE. We illustrate this with an example. Example 1. x 00 Given that y1 = e is a solution to y − y = 0, find another solution. Solution 1. x 0 x 0 x Let us begin by assuming that this second solution has the form y2 = ue .

  • Teaching Physics with Computer Algebra Systems
    AC 2009-334: TEACHING PHYSICS WITH COMPUTER ALGEBRA SYSTEMS Radian Belu, Drexel University Alexandru Belu, Case Western Reserve University Page 14.1147.1 Page © American Society for Engineering Education, 2009 Teaching Physics with Computer Algebra Systems Abstract This paper describes some of the merits of using algebra systems in teaching physics courses. Various applications of computer algebra systems to the teaching of physics are given. Physicists started to apply symbolic computation since their appearance and, hence indirectly promoted the development of computer algebra in its contemporary form. It is therefore fitting that physics is once again at the forefront of a new and exciting development: the use of computer algebra in teaching and learning processes. Computer algebra systems provide the ability to manipulate, using a computer, expressions which are symbolic, algebraic and not limited to numerical evaluation. Computer algebra systems can perform many of the mathematical techniques which are part and parcel of a traditional physics course. The successful use of the computer algebra systems does not imply that the mathematical skills are no longer at a premium: such skills are as important as ever. However, computer algebra systems may remove the need for those poorly understood mathematical techniques which are practiced and taught simply because they serve as useful tools. The conceptual and reasoning difficulties that many students have in introductory and advanced physics courses is well-documented by the physics education community about. Those not stemming from students' failure to replace Aristotelean preconceptions with Newtonian ideas often stem from difficulties they have in connecting physical concepts and situations with relevant mathematical formalisms and representations, for example, graphical representations.
