I didn't understand when they rewrote the function by defining the piecewise function. The numerator made sense, but the denominator seemed a little out of the blue. I am also still having a hard time understanding how it is that convergence helps us to prove these concepts, it seems so unrelated. Even though this class has turned out to be very difficult for me, I suppose it is kind of a good thing. Never before have a gone to every class, done all my homework, studied lots, taken good notes and still not understand. This class is helping me so that I'll have empathy for my future students and previously I have never been in that position.
