From Example Problems

The procedure with and is pretty much the same as with and . In both cases, we want to get to a place where we can do a substitution. With , a suitable is . This is the difference.

So, if you think about it, you can figure out the procedure here, or for any other problem of this type, yourself. When there is an even number of , turn all but 2 into and we'll have a whole bunch of and the derivative of and nothing else.

If we were to do a substitution, we'd do and but we've done enough to not write out the steps.
