WinEdit Latex Editor

A friend of mine mentioned they use WinEdit to originate LaTex math documents.  I checked and it appears it does not give a WSIWYG preview or working environment.  I will have to install to verify.

From Wikipedia

WinEdt is a shareware Unicode (UTF-8) editor and shell for Microsoft Windows. It is primarily used for the creation of TeX (or LaTeX) documents, but can also be used to edit HTML or any other type of text file. It can be configured to run as a front-end for a variety of TeX systems, including MiKTeX, fpTeX and TeX Live. WinEdt's highlighting schemes can be customized for different modes and its spell checking functionality supports multi-lingual setups, with dictionaries (word-lists) for many languages available for downloading from WinEdt's Community Site. It supports DVI and PDF workflow.

Math: Derivation of Matrix Determinant

Which you should recognize as Cramers rule lurking in the bushes.

Now let us take it a little further.  Click into the links below to first see the derivation of the determinant of a 3×3 matrix.  Then clink into the derivation of the determinant of a 4×4 matrix and higher with recursion.
