**Integration by Parts**
*after Henry Reed's*

Naming of Parts
To-day's integration by parts. Yesterday,

We did

frustums and

donuts. And to-morrow morning,

We shall learn

partial fractions. But to-day,

To-day's integration by parts.

Squirrels

Scamper around by the building,

And to-day's integration by parts.

This is the indefinite integral. And this

Is the definite integral, whose use you will see,

When you have to do areas. And this is the loop integral,

Which in your case, you do not get. The birds

Swoop and flutter, rejoicing in good food and freedom,

Which in your case, you do not get.

This is the homework, which is always completed

By the next day's class. And please do not let me

See anyone writing in pen. You can do it quite neatly

If you have a pencil or two. The oak tree

which stood out the window is gone, made into

A pencil or two.

And this is a syllabus. The purpose of this

Is to give you more problems, as you see. We can make it

Change with a breath and a nudge: we call this

Adapting to demands. With a breath and a nudge,

The wind makes the snow fall and glisten:

They call it adapting to demands.

They call it adapting to demands: it is perfectly easy

If you have an hour or two: like the syllabus,

And the schedule, and the definite integral, and the homework,

Which in your case you did not get; see the squirrels

and the birds getting ready for winter, breathing and nudging each other,

and to-day's integration by parts.
