Integration by Parts
Let’s start off with this section with a couple of integrals that we should already be able to do to
get us started. First let’s take a look at the following.
So, that was simple enough. Now, let’s take a look at,
To do this integral we’ll use the following substitution.
Again, simple enough to do provided you remember how to do
substitutions
. By the way make
sure that you can do these kinds of substitutions quickly and easily. From this point on we are
going to be doing these kinds of substitutions in our head. If you have to stop and write these out
with every problem you will find that it will take you significantly longer to do these problems.
Now, let’s look at the integral that we really want to do.
