This week we continued to learn more about chapter 7. We dove into section 7.3 that dealt with revolutions of solids. It is very important to understand the integrals from previous sections of when to integrate either from x or y when setting up the equation formula for solving the volume. We learned two methods in particular. One method we used was called the "disk method". This was the easiest method because all you needed to find was the integral you were integrating and the function to plug into the equation. The second method we used is called the "washer method". This method is very confusing to me. I was absent the day it was taught so I have been a little fuzzy on this topic. However, I get confused of which function/value is the larger R and which one is the little r by looking at the graphs. I am a little nervous going into a test on Monday and being confused on the washer method. For next week I hope to get a better understanding of the "washer method" to solve equations. I believe next week in order to successfully do well in the class I will have to make sure I understand the revolution methods well. The quiz we had earlier in the week I felt I was a little confused on. However, after learning more about these kind of solids on graphs I believe I have a much better understanding therefore should be able to complete a mastery on that quiz pretty well. I believe my participation went well this week. I was engaged in the CCCs and contributed towards my work and helping others when we had a sub. Next week I believe we will learn other methods in solving these kinds of equations with revolutions.
