The COUNTDOWN web site features more than 800 instructional QuickTime math videos and 350 companion worksheets that are devoted to the demonstration and support of effective mathematics instruction. These multi-indexed math movies are organized according to content standards established by the National Council of Teachers of Mathematics allowing viewers to explore specific math concepts at their own pace. Whether you are an educator brushing up on formulas, a fifth grader figuring out equivalent fractions, a grad student completing a methods assignment or a concerned parent seeking an electronic math tutor for your child, this site is a rich math resource available free of charge for your repeated use. The video clips found on this site have been edited from hour-long interactive weekly TV broadcasts on Channel 21 in Chicago.
The calculator can do statistics, best fits, function plotting, integration. It handles vectors, matrices, complex numbers, quaternions, coordinates, regular polygons and intersections. For point, line, plane, sphere, circle Calc 3D calculates distances, intersections, and some additional information like volume and area. Cartesian, spherical and cylindrical coordinates can be transformed into each other. Carthesian plot, polar plot, parametric plot, best fit, fast fourier transformation, histogram, smooth, and others.
This site provides lectures, animations, graphics, tests for teaching precalculus, calculus, trigonometry and differential equations.
Course Communities in Undergraduate Mathematics is a collection of online resources for undergraduate mathematics courses. The courses done so far are one-variable calculus, multivariable calculus, and ordinary differential equations. These resources were assembled and cataloged by separate working groups for each course. In addition there is a pseudo-course, developmental mathematics, obtained from Tom Carey's project of the same name. A working group is currently identifying and cataloging resources for a course in probability.
An online derivative calculator that computes symbolic derivatives of mathematical expressions. User input and results are typeset as graphical formulas.
This is a free textbook which covers material for an introductory course on differential equations with some partial differential equations material, though it assumes knowledge of matrix theory. It includes a section on computing Fourier series of polynomials. It also includes a link to the freely available student solutions manual.
This site provides information on solutions to various classes of mathematical equations. There are exact solutions and methods for solving ordinary differential equations, partial differential equations, integral equations, and other classes of functions and transforms. The Equation Archive allows authors to post equations and exact solutions, first integrals, and transformations. There is also an index of named algebraic, ordinary differential, partial differential, integral, and functional equations. Other materials include links to online forums, information on mathematical software, and links to educational materials, publications, and related websites.
Freebookcentre.net's mathematics section contains links to many technical books offered free online, either as html pages or downloadable pdfs. Books are arranged by subject: algebra, geometry, calculus, differential equations, discrete mathematics, linear algebra, number theory, differential algebra, probability theory, trigonometry, and others.
GoodQuestions is a pedagogical strategy designed to improve calculus instruction for higher-level students by adapting two methods developed in physics instruction: ConcepTests (conceptual multiple-choice questions) and Just-in-Time Teaching (a pedagogical strategy that blends web technology with active learning in classroom situations). The project web site includes class materials, links to math classes where the strategy is being employed, news articles, and information on the project team.
An online integral calculator supporting definite integrals, indefinite integrals (antiderivatives) and improper integrals. User input and results are typeset as graphical formulas.
Investigations is a complete K-5 mathematics curriculum, developed at TERC in Cambridge, Mass. It is designed to help all children understand the fundamental ideas of number and operations, geometry, data, measurement, and early algebra. The curriculum has four major goals: to offer students meaningful mathematical problems; emphasize depth in mathematical thinking; communicate mathematics content and pedagogy to teachers; and expand the pool of mathematically literate students. This site includes descriptions of the units in each grade, K through 5; ordering information; and information on professional-development workshops designed to facilitate introduction of this curriculum.
This site offers 18 curricular modules based on primary historical sources for undergraduate courses in discrete mathematics, combinatorics, logic, abstract algebra, graph theory, analysis of algorithms, data structures, automata and formal languages in computer science. Designed to capture the spark of discovery and motivate the subsequent lines of inquiry, our projects are centered around key historical sources that led to the development of selected topics in the above fields.
This application solves your linear systems.
The "Butterfly Effect", or more technically the "sensitive dependence on initial conditions", is the essence of chaos. This is illustrated an applet of the Lorenz Attractor. The demonstration shows a graphical representation of the time variation of three variables X(t),Y(t) and Z(t), coupled by non-linear evolution equations.
The Mathematical Association of America (MAA) provides a range of high-quality educational resources for educators all across the United States and the world. Recently, they completed digitizing over 114 years of their short classroom materials, and they are now available right here. On the homepage, visitors can look over "Featured Items" to get started, and then they can type in keywords to look for specific items. Recently featured items have included "Proof without Words: Geometric Series", "Museum Exhibits for the Conics", and "The Birthday Problem Revisited". Visitors should also check out the "Tips on Searching" area to help out with their exploration of this archive. Educators will find that the site is worthy of several visits, and this material can be used to illuminate a wide range of mathematical topics and concepts.
