 ``` 2 November 1998 Vol. 3, No. 44 THE MATH FORUM INTERNET NEWS Math for Morons Like Us | Graph Explorer - Cooper | MegaConverter MATH FOR MORONS LIKE US http://library.advanced.org/20991/ Students talk to students about math: a site designed to help teach math concepts. Tutorials, sample problems, and quizzes, designed for those who know some of the basic concepts but seek reinforcement, or who want to review things they learned in the past. The site covers: - pre-algebra - algebra - geometry - algebra II - pre-calc/calculus Interactive resources include a calculus message board, a user-contributed formula database, quizzes, math links, and a place to send feedback. Math for Morons Like Us is a 1998 ThinkQuest entry. http://www.advanced.org/thinkquest/explore/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- ** Reader's choice: GRAPH EXPLORER - Alan Cooper http://www.langara.bc.ca/mathstats/resource/GraphExplorer/ A JAVA-based graphing utility from the Dept. of Mathematics and Statistics at Langara College in South Vancouver, B.C. This applet is designed to allow you to zoom in and out smoothly, or to pan across the graphs of functions that you define. Reader Syrilda Miller writes: "It is the best I have found for teaching transformations. It features full use of parameters, colors for the graphs, zoom in and out, continuous change of parameters, easy editing, and frames for the instructions." You can use Graph Explorer: - to display the graphs of functions that you want to study, either individually or in families labelled by "parameters" such as m*x+b or a*x^2+b*x+c; - to note how the intercepts and other properties of the above examples depend on the parameters, and relate those observations to linear and quadratic functions; - to observe the family of functions given by b^x for various values of b, and identify the number e as the b-value giving slope 1 at x = 0; - to observe, with the aid of the zoom feature, the "local linearity" of various functions; - to explore other topics with the aid of pages of Internet resources for the mathematics student, organized by topic (pre-calculus, calculus, differential equations, linear algebra, statistics) and by category (tools, courses, demonstrations, general catalogues, and organisations/ institutions). http://www.langara.bc.ca/mathstats/resource/onWeb/ -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- MEGACONVERTER - Ben-Cam InterMedia http://www.megaConverter.com/_Conv/cv_home.htm "the Web's best place to figure out what equals what" An ever-growing set of modules for converting and calculating weights, measures, and units. Spin a dial to select the kind of unit to convert: ancient lengths, volume, or weight; angles; area; astronomical distance; dec/hex/oct/bin; density; energy; finance and interest; force; foreign area, lengths, volume, or weight; heat index; kitchen measures; length; mass and weight; metric prefixes; nails (hardware); payment predictor; power, pressure; rgb to hex; shot count; speed; temperature; time; typography; volume; weight in space; wind chill; wine and spirits (fluid measures); wire density or resistance; and zillions (large base ten numbers). The site requires Netscape 3.0 and higher or Internet Explorer 3.0 and higher. -|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|-\-/-|- CHECK OUT OUR WEB SITE: The Math Forum http://mathforum.org/ Ask Dr. Math http://mathforum.org/dr.math/ Problems of the Week http://mathforum.org/pow/ Internet Resources http://mathforum.org/~steve/ Teacher2Teacher http://mathforum.org/t2t/ Discussion Groups http://mathforum.org/discussions/ Join the Math Forum http://mathforum.org/join.forum.html Send comments to the Math Forum Internet Newsletter editors _o \o_ __| \ / |__ o _ o/ \o/ __|- __/ \__/o \o | o/ o/__/ /\ /| | \ \ / \ / \ /o\ / \ / \ / | / \ / \ ```
