As far as anti-derivitives go, I think I get it, and the tangent line is just the derivitive of the equation right? I really have no problem with sketching f from f' as the book calls it, although when I graph the f' to f, I seem to make silly mistakes. The chapter 3 review was fairly easy, and only a few problems really stuck out as difficult to me. The derivitives of e^u and ln(u) are simple enough, but the derivitive of a^u I will have to write down. I'll also have to write down the derivitives of sin cos and tan, and sin^-1 cos^-1 and tan^-1. I think I know how to do higher order derivitives, but I'm doubting myself again. Looking back on limits, I remembered that I need to know limit of x to infinity of sinx/x = 0 and limit of x to 0 of sinx/x = 1. I have a feeling that will come back on the test.
