Rules for Limits if x--->infinity
1. degree of top equals degree of bottom-->ANSWER: top coefficient over bottom coefficient
2. degree is bigger than bottom degree-->ANSWER: positive or negative infinity
3. top degree is less than bottom degree-->ANSWER: 0


Also with limits--->if indeterminate form is created
L'Rule! All you do is take derivative of top over derivative of bottome. If indeterminate form is still created then simply repeat.


NOTE: I have been getting a lot better at substitution. With all the practice I'm starting to recognize things that need to be substituted. Like if you have sin and cos, those are derivatives of each other so you would use substitution.


NOTE: Let's not forget that the integrals of some things are on our chart. Most of them are like ln of something.


NOTE: Remember AREA means to INTEGRATE! I saw that one popped up on the packet.

  1. Just a note. When given like a graph and equation and you're told to find the area of the shaded region, your bounds are the shaded region in reference to the x axis,,,so whatever x values that are included in the area...
