As a physics professor, I’ve discovered that there is one thing more than any other that prevents students from finding success in my algebra-based college physics course, proficiency in algebra. Students who start the course without sufficient mastery of algebra are like students starting a English literature course without being able to read English. If

The extension EPS stands for Encapsulated PostScript and is my favorite filetype for graphics and figures I produce using applications like Illustrator, Inkscape, and MATLAB. Here is how to insert EPS figures into a LaTex document. First you have to use the graphicx package so insert the following after the \documentclass tag and before the

As a physics professor, I’ve discovered that there is one thing more than any other that prevents students from finding success in my conceptual physics course, proficiency in algebra. My conceptual physics course include a significant amount of problem solving and students who start the course without sufficient mastery of algebra are like students starting

Below is code demonstrating how to typeset matrices in LaTeX using the array environment. \begin{displaymath} Q = \left( \begin{array}{ccc} q_{11} & q_{12} & q_{13} \\ q_{21} & q_{22} & q_{23} \\ q_{31} & q_{32} & q_{33} \\ \end{array} \right) \end{displaymath} The code generates a three column matrix with the contents of each column centered ({ccc}).
