A little math help.

Just getting back into algebra for college.

The square root of 5-x +1 = x-2

I really have not wanted to know the unknown!:rolleyes Now 33 1/3% off, is important!:toast

[spurs_2108]

Thanks. It took me forever to figure this out. I had to do the problem like 5 times.

my how ten years have flown by. I don't even know where to start with that.

I am so glad I no longer have to concern myself with solving the above problem!

Kudos to all you super smart peeps who still remember how to.

I get it now. Thanks.

I don't think +1 works for the first question. If you plug it back in the equation you'd get +3=-1 (since there is no sign before the square root, you'd take only the positive square root).

[E20]

Yeah you're right the way I did the problem I got two answers for the quadratic, which is what you should get, but only one of them can be used correctly for the original equation. I haven't taken an algebra course for 5 years so I'm a little hazy. LOL

You guys really need to learn how to format math in LaTeX.

[ShoogarBear]

Does anybody use TeX/LaTeX anymore?

[tp2021]

For condoms.

Does anybody use TeX/LaTeX anymore?

How else do you typeset your mathematical documents?

Nothing like turning your homework solutions in as a printout of rendered LaTeX. My TA was freaking out and asking where the hell I found a solutions manual for my real analysis book and why I would even bother to turn such an obvious photocopy.

Most of these already had their own thread, but I don't think anybody will mind busting them out once again. We may be low on oil, but we're not running out of internet anytime soon.

The critique of Two Girls, One Cup is pretty hilarious, too, but that would probably get this post moved to the Troll Forum.

I always laughed at this one:

This one's the funniest one there though:



Find the height of a building using a barometer
Posted by chewyshoe On October - 24 - 2007

At my first year of college my physics teacher told us this rather amusing story, I’ve never forgotten this story - but I certainly have forgotten everything I learned in that class.

The following question was asked at the University of Copenhagen in a physics exam:

“”Describe how to determine the height of a skyscraper with a barometer.”

One student replied:

“You tie a long piece of string to the neck of the barometer, then lower the barometer from the roof of the skyscraper to the ground. The length of the string plus the length of the barometer will equal the height of the building.”

This highly original answer so incensed the examiner that the student was failed immediately. He appealed on the grounds that his answer was indisputably correct, and the university appointed an independent arbiter to decide the case. The arbiter judged that the answer was indeed correct, but did not display any noticeable knowledge of physics. To resolve the problem it was decided to call the student in and allow him six minutes in which to provide a verbal answer which showed at least a minimal familiarity with the basic principles of physics. For five minutes the student sat in silence, forehead creased in thought. The arbiter reminded him that time was running out, to which the student replied that he had several extremely relevant answers, but couldn’t make up his mind which to use. On being advised to hurry up the student replied as follows:

“Firstly, you could take the barometer up to the roof of the skyscraper, drop it over the edge, and measure the time it takes to reach the ground. The height of the building can then be worked out from the formula H = 0.5g x t squared. But bad luck on the barometer.

“Or if the sun is shining you could measure the height of the barometer, then set it on end and measure the length of its shadow. Then you measure the length of the skyscraper’s shadow, and thereafter it is a simple matter of proportional arithmetic to work uut the height of the skyscraper.

“But if you wanted to be highly scientific about it, you could tie a short piece of string to the barometer and swing it like a pendulum, first at ground level and then on the roof of the skyscraper. The height is worked out by the difference in the gravitational restoring force T = 2 pi sqrroot (l/g).

“Or if the skyscraper has an outside emergency staircase, it would be easier to walk up it and mark off the height of the skyscraper in barometer lengths, then add them up.

“If you merely wanted to be boring and orthodox about it, of course, you could use the barometer to measure the air pressure on the roof of the skyscraper and on the ground, and convert the difference in millibars into feet to give the height of the building.

But since we are constantly being exhorted to exercise independence of mind and apply scientific methods, undoubtedly the best way would be to knock on the janitor’s door and say to him ‘If you would like a nice new barometer, I will give you this one if you tell me the height of this skyscraper’.”

The student was Nils Bohr, the first Dane to win the Nobel prize for Physics. “

This one's the funniest one there though:

:lmao :wow :lmao

That teacher got πr^pwned.
