Begin of lunch box unwrap

oh im sorry rinout my lending of clothes tired u ! oh poor reinout has done such hard work ! but for my concern the devil who cursed CPhill doesnt get tired !lol!by the way im happy my suit helped jack !

u know reinout i could understand only the last line of both of ur notes but it was interesting reading it !i didnt know that these things are provided in the lunchbox now a days !lol!

 gift this from me to Beth for the prom! take care of my dress Beth !

Theorem 5.5:

Beth Likes Rosala's dress

proof:

You know, I find set notation confusing enough when it does not involve dresses, dates and proms!

Rosala, ot is ver nice of you to loan Beth your dress.  It is a lovely dress.  Beth will look very sophisticated!

rosala might be loaning her dress......but she's not loaning her chocolate pastry......!!!!  .....to anyone....

reinout i cant understand a single thing uve written except the las sentence that to half !i am happy she likes the dress !and thank u melody for the compliment !

this ones for jack !im just giving him this for the sake of Beth for bothof them should look equal and not just beth lookin pretty and jack not equal to her !hope he likes it !lol!

O____o oh my god!

Let f,S and Dr be as above.

Define g:S->R as g(x,y) = f(x,y) and let J be the set of suits Beth can wear.

Note that J is a subset of S. Define the suit rosala picked as Jr=(10,10).

Note that Jr = Dr. Then given that Dr attains a maximum on f(x,y) and is therefore the best dress of set D, Jr must attain a maximum on g(x,y) = f(x,y) and is therefore the best suit of set J.

Hence Jr is the suit Beth likes most.

phieuw... 

To put the joke in straight english for rosala and melody (because my current state is called evasive study behaviour).

If Jack is one of all the boys in the world and beth is one of all the girls in the world.

Then (it assumes) there must be some function linking all the boys and girls in the world with their perfect date. So If you enter eg. Rosala you get the perfect date for Rosala.

Now we are looking for the perfect date of Beth, so we enter Beth into the function.

Beth knows from previous experiences that there's a certain type of boy Beth likes to take on a date.

This certain type, which is (off course) a part of all the boys in the world, is a good dancer, a good conversationalist, a gentleman and (obviously) free.

She then states that it was previously determined that Jack is a good dancer, a good conversationalist and a gentlemen.

Since she obviously doesn't know whether Jack is free, she states this is to be determined by the reader.

(which is a joke, since in actual proofs, this is merely a statement saying if the reader is interested he should find out how it works himself)

Since Jack has all the parts of the date Beth wants, he's a solution to the 'perfect date' function. 

Now that was a lesson on set notation 

i found the joke while reading it the first time only but u could give it in "straight english " before ! did u wanted to test our brains or what !lol!

Haha, no i found it quite a funny way to ask your date out.

I didn't think of it myself though. 

I did make up my own proof for your dress off course.

reinout , i think u missed something ! u made ur own proof for all of them !
