When I took calculus in college, it didn't take me long to figure out I didn't give a rat's behind where the mathematical formulas had come from. Just give me the formulas and I'll do the work. I think they made a special classroom for the instructor we had. The only part of the walls that wasn't chalkboard was the door way :wtf: :lol:. Some days it took more than one lap around the room for him to make his point :lol:
