Expand Me

There are times at which cannot be known
Exact values of a term
But approximations can be shown
Taylor can make me less firm

It is too compact, it must expand
Sensitive, small and too tight
But I know with her talented hand
A solution is in sight

You may think this concept is complex
Summing derivatives, but
Taylor expansion is just good sex
Fingers for this aching slut

The first one, strong and deeply sublime
The second, not as severe
The third, slighter and done in brief time
The fourth and success is here

This grouping of terms is not so vast
I know now, my moans profuse
Each addition smaller than the last
This is how to make me loose
