Hope you had a great Christmas, DS.......

See if you can upload your pic.......if not.......maybe I can talk you through the process........

Cause you did Solveit, you just needed to do a rough sketch and you would have got it yourself straight off!   :)

Yes :) i found 25:2=12.5 it is mean that it passes through a point deviding it into two parts i drawed a vertical line through 251 and 39000 and the horizontal throug 245 and 37000 intersection point is 251 and 37000 (D). Thanks Melody ! :)

Pfff it's too easy :) i undertood

Mmm

Well there are far more dots to the right of 244 ft than to the left so that is not a median height.

    So it is not either of the first two

39000f^3 has lots more dots below than above so its not the last one

That leaves you with C or d.

Just count the dots.  There has to be the same number above as below 

and

the same number on the left as on the right.  :)

It is a good question :)

find factor: x^2-2xy+y^2+3x-3y-4

\(x^2-2xy+y^2+3x-3y-4\\ =(x^2-2xy+y^2)+(3x-3y)-4\\ =(x-y)^2+3(x-y)-4\\ \mbox{Let z=x-y}\\ =z^2+3z-4\\ =(z+4)(z-1)\\ =(x-y+4)(x-y-1) \)

Nauseated, how can you make Dragonlance a squire of Camelot   (Or camel lot)  when you are not a knight?

Actually, Sir CPhill did. I just formally declared him Squire Dragonlance –a Squire to CPhill, not the Squire of Camelot. Do you think the Queen will demote the poor kid? If she does that means he’ll be on the Queen’s SOL list as well as Santa’s.

thanks Melody

Hi Soveit,

Perhaps my pic will help you work it out for yourself :)

Are you unwell ?

 No. I’m not unwell --it’s Christmas,so it gives that illusion. The troll alliance wants to petition to have the holiday abolished.  I was dismissed from the troll council and made persona non grata a few years ago when I quit charging tolls on Christmas.  I was reinstated after they found out I was charging triple for the return trip.

There is one consideration in evaluating Bertie’s error count: Some of his presentations are so advanced, very few would know whether he made an error or not.

Nauseated, how can you make Dragonlance a squire of Camelot   (Or camel lot)  when you are not a knight?

I do not think that Queen Guinevere would be impressed with that!

That would have to be the most gracious post you have EVER written Nauseated.

Are you unwell ?

I was looking for a pic for you - I found a couple but this is a G rated site so i could not use them,  

-------------------------------

Seriously though, you are right, knowing which formula to use is a skill unto itself and I am sure you usually get it right.

You do not get it right all the time though, none of us (on this forum ) does.  (Except maybe Bertie)

Something I have always said about probablility:

The correct answer can be explained to you and you can understand the logic of it  BUT that does not mean that you can understand why your original answer was wrong!  Understanding why a wrong answer is wrong can be beyond a person's comprehension.   

This is not really related to what you were saying, it is just another observation!        

Do you want to be shown why, or would you prefer to be guided so that you derive the result yourself ?

The following might be more helpful.  Put the result of one iteration into the expression symboloically, and then expand as a Taylor series:

There were some good times back then, as there are now.  Do you remember Professor Lopez,

Yes I do. She and Kitty were among the few who answered questions in Spanish. 

Prof. Lopez married and has 2 children now.  I suppose she is teaching them mathematics.  

It doesn't always converge to pi.  Try a value for n greater than 2pi for example.  And sometimes it takes a while to get going even when it does converge to pi.  or example, here's a graph where n = 2pi-10^-8

How type y variable?

I don't understand your problem,   :(

أنا لا أفهم مشكلتك،

Thanks DragonSlayer554, I am pleased that you enjoyed your Christmas :)  

I enjoyed mine too. :)

I would love to see your pictures but I do not know about Instgram,

Can't you post them on here ?

Alan's instructions for uploading pictures work well.  

And if you still have problmes uploading you can ask for more help :)

Well I suppose it’s true. I would never presume to compare meself to Bertie even if we did pass the same test.  If I do belong on the totem pole of this forum’s high-end mathematicians, it’s the lowest part – like the part that’s buried in the ground. :)

There is one thing about my magic book of formulae: only one copy of that particular book exists.  My skill set consists primarily of knowing which formula to use. Think of a skilled surgeon who has before his finger tips fine surgical instruments.  He’s an expert at using them but he doesn’t have the skill to create most of them.

Of the many formulas in my book, there are many I can derive, but I lack the skill to present most of them formally. Some, like the one mentioned here, I really do not understand it other than in a broad sense based on computerized analysis.   

This formula may be one of the most esoteric I have. What that formula was used for is amazing of itself. It was used as part of an iterative series to weight oscillating gravity fields of finite space-time intervals over long time-period intervals. It worked well for areas of less than 70 cubic AUs.    

The fact that it would solve Squareroot’s question was intuitive to me more than an immediate recognition of its application –I may not have recognized it except he had posted the result. I’m sure there is more than one way to solve his question.

Wait  . . . You already put me on the totem pole. This was too easy  . . .  You must be a in a Christmas-y mood.  I’m not going to complain, though.  . . . :)

Also  Nauseated,

Thanks for the trip down memory Lane.  It is fun to look back on old posts.  I remember writing that one. LOL

And yes, you have also been here at the forum since it arose from the womb of the primordial soup too :)

There were some good times back then, as there are now.  Do you remember Professor Lopez, I think she was from Arizona.  She was a lot of fun, it is a pity she did not stick around.  Do you remember Professor Lopez and her alter egos Nauseated ?

Hahaha !      

That is great Nauseated,

Could you record it for us, we want to hear it in its entiity!     

You can take up writing songs :D

BUT

Don't give up your day job.  Your kids still need to eat !         LOL

Following Nauseated's formal complaint I have added tn amendment to this post:

Hi Nauseated,

Yes SquareRoot's professor did give you and Bertie both an excellent test result in absentia.  

I am most impressed.

I bring your attention to your own post;

I remember when I was the only mathematician and there were no questions that I could not answer.

Yes, that's true, you could answer them all.  The most common question was 2+2 and the most complex question was 9*9.  So it was sort of like coming in first in a one person race.   LOL

I remember those days too. I was a troll on here even then. There were no scores then just page view counts—my troll posts were quite high. Still, it was barely worth trolling until Melody cracked her whip and had a few rivers and canals dredged. They all need bridges and that was a great expansion of the old homestead.  This troll started feeling right at home.

Here a reference to Melody’s bridge-building skills. 

Lancelotlink gave me a solar powered decoder ring. Consistent with his corporate philosophy, it runs on banana power at night.  In any case, no harm, your squire came to your aid. Good help is hard to find. Hither to and henceforth Dragonlance is now Squire Dragonlance.
