post 14 and 15

So this past week was our Thanksgiving holidays, which was a much needed break. But before this break we learned about many different things. One thing was substitution. The steps for this are
1. Pick out your u
2. Take the derivative of u
3. Substitute it back in to original
4. Then integrate like normal
5. Take all of the u's you get and put them back into the original problem

For old stuff that I know limit rule is not hard at all.
1. If the biggest exponent on the top and bottom are equal then the limit is the coefficient of the highest exponent on the top over the the coefficient of the highest exponent on the bottom.
2. If the biggest exponent is on the top then the limit is infinity.
3. If the bigger exponent is on the bottom then the limit is zero.

The steps for related rates are
1. Pick out all variables
2. Pick out all equations
3. Pick out what you are looking for
4. Sketch a graph and label
5. Create an equation with your variables
6. Take the derivative respecting time
7. Substitute back into the derivative
8. Solve

Some things I do not know are ones like numbers 16, 46, 54, and 91 on the packet we were given to do over the holidays.
