alrighttt, so this week we did more practice ap's. yessssss. and went over both the calculator and noncalculator portions of the test. we even had these papers to write down what was the key words in the problem, and then how to work it next.
ok so, let's go over some stuff.
linearization ... key word is APPROXIMATE.
f(x) = f(c) + f'(c) (x-c)
^^^use that formula.
how to find critical values:
1. take the derivative of the function
2. set it equal to zero
3. solve for x.
taaadaaa.
Limits that go to zero:
If a limit is going to zero, check first to see if there is a +h at the end of top part of the equation.
if there is, take the derivative of the (whatever + h)
& remember disks and washers both have area and volume formula's, which are both the same except one is squared and one isn't. i don't remember which one though.
and can someone explain the shortcuts for finding max and min? i forgot it.

If you are finding max and min values, that means you are finding the y points that are largests.
