Week 6 of this marking period consisted of looking back to the old and diving into the new. We started off with a project in geometry by finding the areas of shapes. This proved to be a fun activity that lead perfectly into chapter 5 where we learned how to find the area underneath a curve because it allowed us to see that there are different ways to find the area of a shape (see pictures above for examples . Using LRam MRam and RRam were quite easy to me because all I had to do was find the area in each rectangle under the curve and then add them up. When then learned how to use Sigma notation to find the area and after this I began to get confused because I do not understand Sigma notation very well. Hopefully after doing the homework for this section I will begin to catch on and then know how to do it for the quiz.

Basically we implement sigma notation to mean we add up all the rectangles that we made in order to find the area under the curve. Sigma just means "sum of." If you continue on in math this notation will come up more. If not, we really won't use it a lot in calculus beyond what you've seen.
