\begin{document} \section{Introduction}This lesson introduces you to the Axiomatic Method. Among other reasons, the logical rigor involved in this approach to geometry, and human knowledge in general, is why it has been taught to school children for 2.3 millenia. Indeed, Abraham Lincoln studied Euclid by firelight in that log cabin in Kentucky. See also Chapter 1 of Hvidsten's textbook. Some students appreciate a concise overview of the material to be covered. The document linked here is of this nature. You should not expect to understand each paragraph on the first reading. It will be elaborated over the first half of the course. You should re-read it periodically to see how much you currently understand of the heart of the matter. \section{Mathematical Writing} For this course you will need to master a beginner's portion of the universal mathematical typesetting language, LaTeX. So you may want to go a bit further and consider writing an essay in LaTeX. The lessons on this website which are written in MathML are in the HTML format. That means, if you want to see how a mathematical formula is conded, you can just look at the source of the web page. Consult the Advice pages for more detail. But it the page is in the PDF format you cannot do this as easily. So here is postulates.tex , which is the source code to the document.
