Hello everyone: I am a new member of this forum and this is my first post. I was referred by an Astronomy.com member and so I decided to check it out. First I would like to introduce myself. My name is John and I am seventeen years of age and a senior in High School. My Calculus teacher also teaches Physics and I am also his aide. Thus I have him for five out of seven hours a day! He is one of the most monotone people I have ever met and the way he teaches is as if he expects us to know this stuff already. Inevitably, I find myself drifting off to sleep during his classes but for recently I have managed to stay awake to learn about derivatives. However, I do need to learn a bit on limits and continuity. If anyone here could help me with these two sections of Calculus, I would be most grateful. I have been interested in learning about math and physics for a long time until I got into his classes. He makes them so very boring. He's a nice person, but I feel his teaching is inadequate and his monotony could put an unruly baby to sleep. Thanks again. Sincerely, John C.
