NonEuclid: Activities - How to get started Exploring. 3.01: The Search for a Counter-Examples NonEuclid is a simulation that allows you to make ruler and compass constructions in the Hyperbolic Plane.
One of the things this allows you to do is make an empirical comparison between Euclidean and hyperbolic geometry. For example, consider the definitions and theorem below : DEFINITION: An angle is a figure formed by two rays that have the same endpoint. The two rays are called the sides of the angle and the common endpoint is called the vertex. DEFINITION: A pair of angles are said to be adjacent if the two angles have a common vertex, share a side, and do not have any interior points in common.

MEDIAN Don Steward secondary maths teaching: algebra. Cuisenaire.swf (application/x-shockwave-flash Object) Pat'sBlog: Why M for Slope. Over the many years I taught I developed a keen interest in the origin and use of the symbols and terminology of math.
When the internet came around I jumped in pretty early with a web page on Mathwords, contributing on the Dr Math and Teacher to Teacher support Math Forum, and for several years, this blog. Over that time there are few questions that come up more often than the reason for the letter m as the symbol for slope in the standard American (and it does seem to be mostly American) linear slope intercept equation form, y = mx + b. Almost no one seems to ask about the b, which is even more curious to me. Dy/dan » Algebra: The Supplement.

Maxima 5.28.0 Manual: Maxima is a computer algebra system, implemented in Lisp.
Maxima is derived from the Macsyma system, developed at MIT in the years 1968 through 1982 as part of Project MAC. MIT turned over a copy of the Macsyma source code to the Department of Energy in 1982; that version is now known as DOE Macsyma. A copy of DOE Macsyma was maintained by Professor William F. Schelter of the University of Texas from 1982 until his death in 2001. In 1998, Schelter obtained permission from the Department of Energy to release the DOE Macsyma source code under the GNU Public License, and in 2000 he initiated the Maxima project at SourceForge to maintain and develop DOE Macsyma, now called Maxima.

Listed below are 34 Investigations, one for each of the 34 sections of Mathematics For Elementary Teachers: A Conceptual Approach, Sixth Edition.
These investigations may also be found at the chapter/section level. The investigations pose questions to generate interest in various mathematical topics from the text and encourage students to formulate and investigate their own conjectures. One use of these investigations is for term papers in which students report on their conjectures and the patterns they find. *Additionally, of the 34 investigations below, 14 also include a data collection software program called Mathematics Investigator. These are indicated by an asterisk. Click on the Read Me files below to open the investigations in a Word file.
Four-Digit Numbers Investigation (Chapter 1, Section 1) Read Me - Four-Digit Numbers Instructions (Word Format) (25.0K) *Triangular Numbers Investigation (Chapter 1, Section 2) Complex numbers. This is an introduction to complex numbers.
It includes the mathematics and a little bit of history as well. It is intended for a general audience. The necessary background in a familiarity with ordinary real numbers (all positive and negative numbers and zero) and algebra.
