Does anyone want to compare answers for the problem set?

This weekend I worked on that problem we were doing in class friday. Let me say, pretty challenging! Kind of cool though. You really had to know the definition of a derivative, that its the slope, so its equal to (y1-y2)/(x1-x2). It was fun, but really hard. I think a problem like that is better to do in a group, so we can bounce ideas off each other. It's a bit much to do by urself. I probably couldn't have done it if we hadn't started in class. Anyway, I think I got an answer.

Ok so today was our second test, and it was alot harder than the first! Alright, maybe not so bad, but definately more challenging because we could not use calculators. I really had to think for some of them. My problem was that I would look at a question, panic, and skip it. When I went back to it, it turned out to not be too bad. My favorite problem was the one with the e^(i won't say in case someone has not taken the test)/ln(ditto). It was cool because it was more theoretical. I had to use logic to figure it out. Hopefully I got it correct. I also liked the second problem we had to do (the one right after the table). That is something that I would not have thought to do before. I like learning different ways of thinking to solve a problem. Anyway, that's all for now.

Ok, I was doing the limits worksheet, and was wondering if anyone can explain to me number 36. I do not understand why the domain does not include anything between and includig o-1. Also, I wanted to know if anyone wanted to compare answers to 13, 27, and 3o, because those were the ones I was unsure about. I did like number 17, because at first I had no clue how to solve it, then I remembered the rule about the limiit sinx/x=1 as x->0. Then the problem was easy! Also, btw, the greatest integer function came up (no 11 and 12), so I am glad we talked about it in class. Overall, I am getting much better at finding limits. Also, I find it easier sometimes to graph the function and use a table to find the limit if Ican't simply plug it in, rather than doing it algebraically. Hopefully that will be ok on a test (yes, no Mr. Flint?). It is just helpful to see an actual picture, and makes it less abstract.
