To start off with the final (third) trimester of this course we began looking at chapter 7. Chapter 7 is the last chapter to be learned for the Calculus exam. Because of the weird schedule with cancellations of delayed exams we went at a little bit of a slower pace with the two first sections. The first section, 7.1, dealt with applications of integrals. This included interpretation between velocity, acceleration, displacement, ect. Because most of these problems were story problems, I struggled with it the most. For this section it was important to remember the standing, velocity, acceleration, and juel rules for derivatives when solving the story problems for anti deriving. However, i grasp the concept of finding the total distance well. i understood the reason for the absolute values of the integral of velocity to find the the total distance. The reason for the absolute values is because you are adding the positive and negative values not just the displacement mechanism. In 7.2 we dove deeper into integrals but ones where we had to solve for their areas within a plane. These areas varied between finding them inside bounded areas. For solving these problems it was important to remember a few specific rules. I had a little trouble with the problems that had you integrate with respect to y instead of x. I got confused on what places to look for the upper and lower bounds to plugged into the equation. However, with practice with the homework, I got more used to dealing with such complex problems and it began to get easier to grasp. I believe my participation went well this week, and I was engaged to ask questions to problems that I needed extra help on. Next week, I know we will have a quiz over 7.1/7.2 and will continue working on further sections within this chapter. I will have to try my best not to fall behind and get caught up with "senioritis" and stay focused in class.
