Chapter 13- Section 6

This past week we learned Chapter 13, and completed 13-6 on friday to finish up the chapter before the holidays. We had to learn this chapter quick because we needed to finish so we could review before our midterm. For the unfortunate students who are not exempt, we will be taking a chapter test and preparing for the midterm exam that alot of us are worried about passing. The most recent section we learned is 13 – 6. Overall this chapter has been prettty simple. Please excuse my examples for this section, it is kind of hard to do without an image like we've drawn in our notebooks.

• For the problems we are solving in this sectin a “sigma” is drawn for every problem.

• A sigma may look like an E to you, but it is not.

• A sigma is a series written in a condensed (not as long) form.

• At the top of the sigma, there is a number called a limit of summation.At the bottom, there is a letter that will always equal a number.

Ex. K=9i The k would be the index and the number is another limits of summation.And in the middle there is an equation called the summand.

• Just follow directions to complete the problems you are given of this type. If it asks for a particular piece of the sigma, you just find it. If it asks you to evaluate, you expand the sigma and solve it. If it tells you to expand, you just expand and stop there.

It's pretty difficult to show you exactly what to do on the computer, and without a picture, but i tried my best to sum it up.
