Sept 2 Introductory stuff. Limits as a way of finding/describing the best answer you can get to a problem (such as 0/0) that doesn't directly have an answer.

review The test will have derivatives on them. A lot of derivatives. Some will require implicit differentiation. Some will be word problems. Some will be related rates problems. One will probably ask you to prove the formula for tan, sec, cot or csc. Practice taking derivatives.
