13-4

I hope everyone had a great Thanksgiving holidays! But unfortunately, we have to go back to a few more weeks of school before Christmas. Before the holidays, we learned chapter 13, which is the last chapter before our exam. This chapter was pretty difficult for me, so I will need a good review when we go back to school tomorrow. Section 13-4 was sort of simple because MOST of the time there were answers given by looking at your notes. The notes we were given are:

For Fractions:

1. If top degree = bottom degree; answer is coeff
2. If top degree > bottom degree; answer is +/- infinity
3. If top degree < bottom degree; answer is 0

If none of these rules apply, the you use the table in your calculator to find out which number it is approaching.
For example:

1. Lim/n->infinity n^5 +4/ 6n^2 – 7n

The degrees are 2 and 5. The top one (2) is smaller than the bottom one (5).
When you look at your rules, they state that the answer will be 0.
That is your final answer, so these types of problems are pretty simple.
