If you go back 40 years ago in the EAA (Experimental Aircraft Association), you will see a very similar but simpler homebuilt aircraft called the Delta Dyke. This new one has the same concepts, but more bells and whistles.

They are actually waveriders -- a quite specific subset of lifting bodies, optimized for hypersonic performance.

And if you ever stumble across an infinite legged horse, a spherical cow, a cat with nine tails, and a white zebra, you can be pretty sure you have entered the realm of the mathemagician from "The Phantom Tollbooth".

"...The USDA once wanted to make cows produce milk faster, to improve the dairy industry. The foremost mathematician of his time offered to help them with the problem. Upon hearing the problem, he told the delegation that they could come back in the morning and he would have solved the problem. In the morning he handed them a piece of paper with the computations for the new, 300% improved milk cow.
The plans began:

Did anyone else catch the error in the limit problem. That first one should be negative infinity.

Shouldn't it be zero not infinity or negative infinity?

lol... i like the solve for x "here it is" one... my friend attempted that once... that same friend answered a question with x... where x = the correct answer and got it right simply because our teacher didn't want to deal with it.

Actually it depends on the direction you approach. If you let x go to 8 from the right side of the number line, it is indeed infinity. From the left it is negative infinity.

The limit is approaching two different directions(negative infinity and infinity) from different sides. Thus, the limit does not exist.
Haven't any of you taken Calclus before?

Sorry to break it to you guys...but CALC II talks about divergence of functions. I would recommend reading.
On a side note...Those types of limits are extremely useful in physics. So learn and love them :)

@andy:
Also, in physics, we don't worry about minus signs. If something is a positive quantity when it should have been a negative one (which you know from "physical reasoning" ... this is a proof for physicists) you just change the sign. You may also optionally comment "must have lost a minus sign somewhere".

But there's a little mistake in the joke about Jesus... to have a parabola, you need one of the variables to be squared, but the other one must remain lineal... meaning each one represents an axis (x or y).
So it should be like "3x squared plus 8y minus 9" if the parabola was parallel to Y, or "3y squared plus 8x minus 9"...or whatever, if it was parallel to X.
Sorry for my English.

Proof that Women are Evil
Women consume Time and Money-->
Women = Time*Money
Time is Money--> Time = Money
Substitution --> Women = Money^2
Money is the root of all Evil -->
Money = Sqrt(Evil)
Square both Sides --> Money^2 = Evil
Substitute --> Women = Evil
Enjoy

I once graded a paper where the student knew the end result but couldn't quite get there because of a zero in the numerator and a zero in the denominator. In a fit of pseudo-genius, the student claimed zero divided by zero was one and his proof worked.

They forgot the annihilator function. Which is something that we made up when we got bored in precal with functions.
The Annihilator Function = The Square root of X divided by the Square Root of -X.

Regarding the limit problem, there is no such thing as negative or positive infinity. Infinity is infinity! That's all!
One more thing: as X approaches 8, the equation approaches to one divided by zero, which in Math means infinity (try yourself...).

"Regarding the limit problem, there is no such thing as negative or positive infinity. Infinity is infinity! That's all!"
That's not true. In simple terms, a limit of infinity means the function increases without bound, while a limit of negative infinity means the function decreases without bound.
The formal definition of
lim(x->a) f(x) = -infinity
would be
For all e in R, e > 0, there exists d in R, d > 0 such that if |x - a| < d, then f(x) < -e

@murripita
actually there cant be 2 different variables in the parabola... its right how it is.. because if you have a graphing calculator, you have to have Y= and then the equation. it makes a parabola how it is written.. oyu should check your facts before posting a comment for all the world to see.

And the information about “Boh” is something that'll definitely make people think I'm cool at parties.
“Mothra” must be the most freakiest idea. I don't know, there's something freaky about moths to me. Especially giant sized ones. Maybe it's because they're just so weird and mysterious. I mean, they're beautiful creatures, but I'm sure they would take vengeance on us if they became a giant Mothra.

About that bit on mailing back the empty envelope... I wouldn't do that if the envelope has a digital data bar on it.
I almost ended up with a subscription to the New York Times that way once.
You see, opening the envelopes is expensive. Reading the digital data on the envelope is cheap - AND the only reason (most people, normal people) send the envelope back to to get the subscription that was offered.
So they just scan the envelope and give you a subscription. They already have your address - it was on the subscription offer they sent you that started all this.
Seriously...

My favorite thing to do to telemarketers is answer and sound excited, but ask if you can put them on hold. Without waiting for a response, put them on hold and see how long they wait before hanging up. It's worth having a phone with this capability for just this reason.
One woman called me back complaining that I had left her on hold. My reply: "As annoyed as you are that I did that to you, I'm even more annoyed that you're wasting my time like this in the first place! In fact, I'm so annoyed, that I'm going to put you on hold again". I put her on hold.

I would think that since we see & perceive A & B as differnt colors then logically they are different colors. If you open the picture in Photoshop and measure the color values the later may be true but i still think that certainly in this case seeing is believing. Thats just my personal opinion & observation.
Btw, Excellent Web-Site & Thank You for posting all this wonderful stuff...
