I just wanted to say thanks for the math class. The Mathematica lessons were great for visualizing the material and getting a grasp for how linear algebra works and how to use it. I took a linear algebra class several years ago as part of my bachelos degree in electrical engineering. I remember not enjoying that class very much because it was full of proofs and theorems that I did not understand very well or how to apply to the real world. This class was a much better experience!
The most useful thing for me about these courses is the fact that I when I do need to use material from any of these classes, I can picture the problem in my mind and have little trouble setting up an answer. If I were armed only with equations and paper and pencil, I wouldn't even know where to begin.
