Hi! I like differentiation rules because they're straightforward. If two terms are multipled together, we use the product rule. If they're divided, we use the quotient rule. The reason why I think we're anxious about antidifferentiation rules is because there are no guarantees that we're even on the right track. There are guidelines that we've discussed over and over again, but as we all know, sometimes we still end up being on the wrong road. As with everyone in the class, I don't feel the best about this unit either. I DO believe though that we'll get through this, and we'll turn out alright. Remember that we took this class, among other things, to get exposed with the material? to be prepared for university? Well, I say let's work our butts out right now too, cause if we don't, we're just wasting our time.

I am not even going to lie and say I understand even the simplest part of calculus . . . it's some hard stuff. I really don't understand much of the material. I just get confused with anti derivative and derivative and the chain rule, integration by parts. There's too much going on in one problem. My brain's exhausted just from thinking about The composite of functions and the product of functions. I really wish I understood calculus but I don't think that math is one of my strengths as some people are good at some things other people are not. I'm just trying to hang on to this class and hopefully come out of it with some knowledge and hopefully it will help me later on in life and if it doesn't at least I can say I tried. So what am mostly confused about is the general stuff like how to use integration by parts otherwise I really don't know.
I am going to go and try to attempt the chapter 7 review one more time and hopefully I'll get some of my confusion cleared up.

What did we do today?

We discussed how the pre-test went with the substitute and the multiple choice questions were pretty straight forward and no one really had any problems. What did leave us all puzzled was the long question in the back, the "open response".


The question was . . .

(1) Let f be a differentiable function such that f " is continuous and f and f ' have the values given in the table below.

(now I wished I had the smart board so I could draw the box like Mr. K had done in class..ah the wonders of technology, I honestly can't keep up with it.)




Don't forget the mnemonic " LIATE ".

L ogarithmic
I nverse trignometric
A lgebraic
T rignometric
E xponential

So an example problem that we did that even got Mr. K, who's a math gyro (uh I don't know if I am using that word right) thinking was . . .



So to review . . .

+ When the integral is a composite of functions, you are better off using substitution.
+ when the integral is a product of functions, you are better off using integration by parts.


Last but not least next scribe is Suzanne.

Everything was quite clear when we started this chapter. That is, until we got to 7.6 everything I thought I knew completely left me. I'm not sure if I'm ready for this test. The pre-test was going great until the open response question. My confidence just left me. For the next couple of days, I'll have to do some MAJOR reviewing.

Ants? Geese? Calculus?

Concerned after reading your BOB's and wondering if you've forgotten these:

How much you supported each other

"Lessons from the Geese"

Yes, it's second semester. Yes, the schedule is hard. And yes, there's so much to do--

Didn't you have something pretty special? Is it lost? Can it be found?

all i can say is that this unit is very hard. it made it more difficult because we only had class every other day so it was hard to remember all the things that was going on. also it was hard to do all the homework since there was alot of other homework from other classes. but i know that it is all my fault lol, i cannot blame anyone. next time i will be sure to do all my homework. p.s. i don't think i am ready for this test lol
