It seems like if I could understand this one problem that it might shed light on a lot of other things. Can anyone help?" - Shelley Walsh The thread references an essay by Ralph Raimi, "On Solving Equations, Negative Numbers, and Other Absurdities," at http://www.math.rochester.edu:8080/u/rarm/equation.html. ______________________________ + ______________________________ AP-CALC - the Advanced Placement Calculus mailing list, hosted by the Educational Testing Service (ETS) and archived at: http://mathforum.org/epigone/ap-calc/ - DE MOIVRE'S THEOREM (2 Feb. 2000) http://mathforum.org/epigone/ap-calc/clehleeblex/ "Can someone provide a motivator for studying de Moivre's theorem either (1) because the student will need it in a future math course he/she is likely to take, or (2) because of its application to real world problems?" - Norman Mikalac ______________________________ + ______________________________ MATHEDU, a mailing list set up to discuss issues in Mathematics/ Education at the post-calculus level, and archived at http://mathforum.org/epigone/mathedu/ - The Real Numbers (17 Feb. 2000) http://mathforum.org/epigone/mathedu/keetwerdthang/ "I have used this construction of the reals in my Real Analysis course for half a dozen years now, and it has tremendous pedagogical benefits...." - Mark Bridger And see other recent related threads about the reals and calculus: http://mathforum.org/epigone/mathedu/whingbumflerm/ http://mathforum.org/epigone/mathedu/pewhuyar/ http://mathforum.org/epigone/mathedu/golyanpex/ http://mathforum.org/epigone/mathedu/freldneldshox/ http://mathforum.org/epigone/mathedu/dweldcrangquar/ http://mathforum.org/epigone/mathedu/flunflalshi/ ______________________________ + ______________________________ HISTORIA-MATEMATICA - a virtual forum for scholarly discussion of the history of mathematics in a broad sense, among professionals and non-professionals with a serious interest in the field, archived at http://mathforum.org/epigone/historia_matematica/ - Indian astronomy and mathematics (14 Jan. 2000) http://mathforum.org/epigone/historia_matematica/pawesming/ "Indian 'tables' of planetary parameters are lists first appearing in treatises of the middle of the first millennium CE. The suggested re-datings of the Vedic texts to the fourth millennium BCE or earlier, which have been proposed in various forms over the past couple of centuries, are based on attributing a very high degree of precision to some statements in them about the relation of star positions to direction and seasons...." - Kim Plofker Astronomical event-dating of the Vedic texts, Indian mathematicians after 1000 A.D., the heliocentric model of Aryabhata, Ptolemy and Copernicus, and more. ______________________________ + ______________________________ We hope you will find these selections useful, and that you will browse and participate in the discussion group(s) of your choice.
