The Magic Square

Posted Image


The Journal of Recreational Mathematics published this remarkable magic square, composed by a puzzlist who at the time was a prison inmate.

The large 13 x 13 square is magic that is, each row and column adds to the same sum but so is each successive nested square, from 11 x 11 down to 3 x 3.

The magic constant of each square is 10,874 smaller than the last.

And every cell is prime.

find the differential equation...solve: (3x+3y-4)dx +(X+1)^2 dy = 0

clue: it is best solve if you use the method on solving linear differential equations :P

I get disappointed yesterday when one of my partners (a teacher that is) told me that he failed in coaching one of his students correctly. That he was not able to come up a correct solution particularly in determining the Trigonometric functions et al.. Sigh.

Parlay bet or combo bet..use 7 consecutive win where 1 bet becomes 2 -4-8-16-32-64-128 then cash out the money.. An be applicable in playing roullette or baccarat.. Instead of betting 1:1 is not practical because we connot out guess the trend.. In short if your winning increase bet ..if your losing remain at 1 bet .. Parlay bet can always catch up to the loss of single bet.. Thats how i make my money in gambling.. Quota lang kayo.. Sabay alis na..

“No mathematician in the world would bother making these senseless distinctions: 2 1/2 is a "mixed number " while 5/2 is an "improper fraction." They're EQUAL for crying out loud. They are the exact same numbers and have the exact same properties. Who uses such words outside of fourth grade?”

― Paul Lockhart, A Mathematician's Lament: How School Cheats Us Out of Our Most Fascinating and Imaginative Art Form

 

 

That I agree, except the phrase "senseless distinctions".  Every level has its own distinctions that need to be explained (and provide drills and exercises). They can be taught as early as second grade. Then again, it differs on the curriculum that any school has been instilling.

if any number raised to 0 is 1;

and 0 raised to any number is 0;

 

then what is 0?

It's still 1.

Now, before you ask me to explain, prove you're not stupid first and that you've done above ave math before (on other words, you would understand). Because the last thing I would want is to talk s@%t like these for free.


I'm more inclined to believe that you have better things to attend to than this--- like something that would, at the very least, make you a peso richer or something that would get you an inch closer to getting laid.


Now, if it will enrich your life to know from a drunk man, hit me with a PM.


But here's the idea: the sun shines prettier if 0^0 = 1 for math guys. Earning a living with numbers. No. I've yet to earn a cent knowing this. And no, it's not getting me laid.

whoa!

 

don't get too excited!

i apologize for rousing any negative emotions! (i detect a hint of hostility in the reply.)

 

i just posted that as something to think about. ....or perhaps discuss.

 

 

going back to the topic. i would think that 00 is undefined.

 

and of course, i could be wrong. (...or perhaps not!)

 

 

btw, being smart (not just knowing what 00 is), can get you laid, ...or at least get you in that direction.

what is the biggest prime number?

 

prime number - a number that can no longer be divided and can only be divided by itself and 1. example ~13. another is 29 and 117. so again, what is the biggest prime number? :)

if any number raised to 0 is 1;

and 0 raised to any number is 0;

 

then what is 0?

 

Some say it should be defined as 1, while others believe it is 0 and some think it is undefined. And the arguments go on and on. When it could simply considered indeterminate*.

 

* You may refer to  L’hopital’s rule  in this case

^This is categorically one of the unsolved problems in mathematics. To determine such is likely referring to Moser's worm problem. Go figure.

Given: (0; 2); (1; 3); (2; 6). Determine with the method of least squares the coecients c and d of the function f(x) = c edx. Note that the parameter d occurs
nonlinear!

What is the derivative of X with the power of chuchu.. langya buti pinasa ako ni prof. Lahat ng quiz ko walang pumasa pero perfect attendance ako. Langyang calculus yan.


Pero sa totoo lang wala syang naitulong ssa buhay ko. Mas gamit pa din algebra. Hehe
