Updated Maths

I have updated the Maths text to include a section on completing the square; some rearranging has occurred. And I added some nice graphs; some of the graphs need to be replaced with "more professional" looking graphs.

Does anybody know of a program for Linux or Mac where I can put multiple graphs, label points, put custom labels on the x and y-axis, and export as *.png files?

I am also going to try and make some video lectures to embed into the wiki for students to review with their notes and homework. I have a video camera ... does anyone have info on video editing software for linux?
