Last week we were pretty much taught all of chapter 13. It's all very easy as long as you remember your formulas.

The easiest for me was 13-4 so ill do a few problems from that.

FORMULAS:
if the degrees at the top is = to the degrees at the bottom then the answer is coefficient.
if the degrees at the top is > than the degrees at the bottom then the answer is +/- infinity.
if the degrees at the top is < than the degrees at the bottom then the answer is 0.
--if none of these rules apply then you would just plug it into your calculator using a table.

EXAMPLES:
2n^4/2n^3
**2nd rule applies!
since 4 is greater than 3 your answer is infinity.
* but is is positive or negative?!
POSITIVE INFINITY.

4n+1/4n
4n is = to 4n so you are left with 1.
your answer is 1!

HAVE A GOOD WEEK OFF EVERYONE :)
