    I really believed that you guys did a good job. I understood how you came up with the solution and now with the help of you boys I can solve this part c problem.

    However one note for next time, show all your work in one area. Because when you showed the final equation, I couldn’t remember the work that you had showed before and didnt know where you got the final equation from because it was erased. I went back to read it and understood it, but just a tip for next time. Otherwise it was very well done and the explanation was very clear. Great job!

    Also I like the music in the beginning and end.
