It's Danny! The day started off with a multiple choice quiz which we will be having every class in preparation for the final exam.

After that Mr. K gave us three integrals to antidifferentiate. When solving these three questions you must consider these two derivative rules:

Now onto the questions and solutions:

QUESTIONS:

SOLUTIONS:

After that Mr. K talked about "Trapezoid Sums" and "Midpoint Sums". I'll sum it all up in four simple diagrams.

For Trapezoid Sums when the curve is concave down, the sum would be an under estimate. When the curve is concave up, the sum would be an over estimate.

For Midpoint Sums, if you rotate it and make it a line tangent to the curve you'll see that when the curve is concave down, the sum would be an over estimate. When the curve is concave up, the sum would be an under estimate.

Well that's all I was able to muster up for this class, as you all know Charlene was the next scribe, her post is already up. Enjoy!

I also have a very important announcement to make. Even though I was convinced to stay in the course by Mr. K himself I truly believe now that it's best if I don't continue on. I experienced something in our last class that couldn't be a better reason for my leaving. I was having trouble with completing a chart, not only because I was unaware of the fact I was doing my task improperly, but also because there was something in there that I SHOULD'VE KNOWN from past pre-calculus courses that I completely forgotten. That explains to me that I haven't done my past math courses to the best of my ability, therefore hindering my learning experiences in my present math courses. I've already begun trying to fix up my past by taking my PRECAL 40S course again. This decision hopefully will allow me to take Calculus again in University, and this time understand things completely with the mind set of thinking I know material I should know and that'll make things easy for me. One last thing, I know Mr. K you tried to keep me in your class and you succeed. However, this time I've decided and no matter how disappointed you may be, I feel this is the right thing for me to do in my life and my soon to be career in education. Please I'm not asking you to agree with me on my decision, but I'd like to know you're always there for me when I need you. I'm terribly sorry Mr. K, but I'm not going to ask for your forgiveness on my decision.

It's really taking much too long to get this scribe post published. Any questions about the content should have been discussed with me the day of the class.

What's going on Danny?

Sorry Mr. K I'm going through some problems with a few things that aren't directly related to school and probably shouldn't be discussed on a blog. But as you can probably see already, I've expressed some of my feelings for the course and my decision is final.

Danny, from what you've written it is clear your mind is made up.

I respect the choice you've made. I think it's a sign of maturity to recognize when there may be holes in your education and to decide to go back and take a course over again after you've already received credit for it. I would never try to convince you to do something you didn't want to do. I don't believe there is anything about your decision that you should appologize for or make you think of "asking forgiveness."

As for being there for you when you need me, well, once you've been in my class you can always return ... for some math help or just to chat; besides, you're still in my pre-cal class. ;-)
