Haply May Remember, Haply May Forget

When I am dead, my dearest, 
Sing no sad songs for me; 
Plant thou no roses at my head, 
Nor shady cypress tree: 
Be the green grass above me 
With showers and dewdrops wet; 
And if thou wilt, remember, 
And if thou wilt, forget. 

I shall not see the shadows, 
I shall not feel the rain; 
I shall not hear the nightingale 
Sing on, as if in pain: 
And dreaming through the twilight 
That doth not rise nor set, 
Haply I may remember, 
And haply may forget.

Suggestions

This blog seems to be becoming "Mostly Math" instead of "Mostly Poetry." Once again I'm posting one side of a "private" math conversation.  Feel free to take it or leave it - or try to figure out what is going on!

******************

Here are copies of a few problems involving the graphing of rational expressions from my precalc notes.  My notes are usually pretty sloppy - work presented on the board being prettier, but, hopefully, this gives you some ideas.

Rational Graph Problem 1:


Rational Graph Problem 2:



And now moving on to math that I think is prettier, but I'm not sure why this image decided to go in upside-down (and no matter what I do they won't flip)!!  This is the beginning of my notes on the binomial theorem, which relates to combinatorics and Pascal's Triangle:

Binomial Theorem Introduction:





And, last but not least, we have Mathematical Induction.  Part of why I think this is pretty is because you often get to use sigma notation in the proofs - see the second-to-last and third-to-last pictures, although there's not much sigma notation there.

Mathematical Induction:






I wish we lived closer!  It would be so much fun to go over these with you rather than just sending pictures.  I also wish I had time to Skype right now, but this semester is TOTALLY kicking my butt!  A good resource for further explanation of these topics is the Khan Academy videos.  The best way to get there (to navigate) is to go to YouTube and then search for the topic and type "khan" - rather than trying to go to the Khan Academy site, which for some reason wants you to sign in, even though it's free, and that makes it a little hard to navigate.

I hope this helps!!!!

The Poem as Mask

When I wrote of the women in their dances and wildness, it was a mask,
on their mountain, gold-hunting, singing, in orgy,
it was a mask; when I wrote of the god,
fragmented, exiled from himself, his life, the love gone down with song,
it was myself, split open, unable to speak, in exile from myself.

There is no mountain, there is no god, there is memory
of my torn life, myself split open in sleep, the rescued child
beside me among the doctors, and a word
of rescue from the great eyes.

No more masks!  Mo more mythologies!

Now, for the first time, the god lifts his hand,
the fragments join in me with their own music.

~ Muriel Rukeyser (1968)
