This week in AP Calculus, we learned how to find the area under a curve. Approximate and exact, well as exact as we can possibly get. USING RECTANGLES!!
First we learned about RRAM, MMRAM, and LRAM. No, not the computer kind of RAM. I'm talking about the Rectangular Approximation Method. There's three types because there's three ways that you could use this RAM. You can use it by having the right side, left side, or middle of the rectangle hitting the curve. Whichever one you use, the most accurate would be the MRAM, or by drawing the middle of the rectangle witting the curve. This is because of the amount of wasted space that does not get accounted for in the calculation of the area when using LRAM and RRAM.
Aside from the RAM stuff, we learned more uses for the sigma notation and the integral stuff. We learned that you can find the area under a curve by using Integrals.. WOW.
Overall I didn't think that the concepts were hard. They were pretty easy to grasp and understand. They're nothing like optimization and related rates that's for sure.
