Although I have no clue how they work, but I remember from Calc I and II, that on the mid term and final exam, if the formula calculations were correct, I'd connect the dots and draw these cool ass curves. 
It's usually a sigh of relief during a tense moment where u feel your parent's money, your raping the books (i.e. studying), and your guilt trip about that 3 hour PC break you took so u procrastinate and finish the next level in WarCraft; was all worth it.
Ah - Calc I Math 101 = 70%
Calc II Math 102 = 60%
both passing marks
