How do you take the definitive integral of a function, when trying to find the area within the integral of a to b?
[a is always the smaller number]
[the integral is always defined on the x-axis]

1.) Find the antiderivative of f(x)
[Don't add the +C at the end]
---------------------
2.) Your function is now:
f(x) = the antiderivative of f(x)
---------------------------
3.) Find f(a)
----------------------------
4.) Find f(b)
-----------------------------
5.) f(b)-f(a)

What are tips for finding the antiderivative in which there is a 'u'?
----------------------------------- |
|
Definition
1.) Find u'
--------------------
2.) Set the original function next to 1/u' and factor out common factors between the A value of the original function and u'.
-------------------------
3.) Multiply them together
------------------------
4.) Take the antiderivative of the function unless the function is exponential in which for some reason you just add "+C", substitute the value of 'u' back in, and your done.
