MathDrawer: A feature-rich mathmatical plotting application

MathDrawer was a project for my Visual C++ course. I was so excited about programming for Windows with this powerful language that I went far beyond what was required for the project. The end result is this: a rich featured plotting application that supports many trigonometric and other functions. It has three modes of operation: drag mode to let you set the scale of the graph by dragging the plot area, percision mode that will make the mouse pointer snap to the curve, and finally scroll mode which is like drag but scrolls automatically as you move the mouse. The application also lets you export the graph as BMP file. I'm sure there are other great graphing applications out there but this one demonstrates a lot of concepts in MFC and Windows programming. Vote if you like it, and don't forget to leave a comment or two.
