This website is designed for educators who wish to extend the concepts of the math curriculum beyond the pages of the text. Google Earth is the dynamic tool that will be used to accomplish this. Google Earth provides startling clear satellite views of the globe in an interactive 3D environment. Beyond the visual, users can add placemarks, annotations, photos, and models, as well as measure distances and draw paths.
A list of links to useful mathematical textbooks available for free on the Internet.
They are all legal and maintained by their authors or by the legitimate publisher.
All the documents are in English. They are in a printable format - Postscript
or Adobe Portable Document Format. You are free to download, read and print them.
Here are some links to other sites offering lists of free mathematical textbooks.
Using only elementary geometry, determine angle x. Provide a step-by-step proof.
You may only use elementary geometry, such as the fact that the angles of a triangle add up to 180 degrees and the basic congruent triangle rules (side-angle-side, etc.). You may not use more advanced trigonomery, such as the law of sines, the law of cosines, etc. There is a review of elementary geometry below.
Math uses made-up rules to create models and derive relationships. When learning, I ask:
* What relationship does this model represent?
* What real-world items share this relationship?
* Does that relationship make sense to me?
Use SAGE for studying a huge range of mathematics, including algebra, calculus, elementary to very advanced number theory, cryptography, numerical computation, commutative algebra, group theory, combinatorics, graph theory, and exact linear algebra.
As our "Annals of Corruption" series unfolds, readers will see that Feynman's account is as timely now as it was when he wrote it. State adoption proceedings still are pervaded by sham, malfeasance and ludicrous incompetence, and they still reflect cozy connections between state agencies and schoolbook companies.
