(I'm not sure how you're meant to type a matrix).

Eigenvector = (1,-1) -> Eigenvalue = 2

Eigenvector = (1,1) -> Eigenvalue = 4


Those vectors should be verticle, obviously

l=3±1= 2 | 4

v=<a,b>

3*a+b=l*a
a+3*b=l*b

a=-b | a=b

v=<1/√2,1/√2> | v=<1/√2,-1/√2>

Actually I just finished :p

And quaker: you can take out a factor of 1/√2 from both those eigenvectors, as they should really be written Eigenvector = x(1,1) etc. So the 1/√2 can just be part of your variable x
And surely you could have done that matrix by inspection anyway :p (at least just to get the eigenvalues)

I just use MATLAB to get eigenvalues - much quicker. Particularly when you're dealing with huge matrices. Also nice and quick for inverting matrices.

Here's a good one - what is a typical OPR for a modern high BPR turbofan engine? (I'm not giving clues for the TLAs - you have to figure those out for yourself :p)
Somewhere between 75 and 100. Or, at least that's what it was anyway, I'm not sure about modern ones, but I'd say around 100 anyway.

Simple question:

What major event in history took place on August 15th 1947 involving a student from the National College in Lahore?
India became an independent nation. I'm sure that student probably had a hand in it...
Are you sure you don't mean August 14th? Because that would involve a whole lot more students from Lahore.

Does Dr. Franklin Ruehl really like ketchup and sugar?
Yes.

When would Geohashing be useful in the Banff & Buchan area of Scotland?
Whenever someone in the Baniff & Buchan area wants to make an XKCD reference.

Are there any other XKCD fans out there, in the UK?
Yes.

Nope, it was the 15th

... and yes, im sure there was more than just the one student (Bhagat Singh) that had a hand in the independence of India (i doubt there were many more from the same college), but it is said that after Hari Shivaram Rajguru, Sukhdev Thapar and Bhagat Singh were excuted that Britain and military forces would leave India due to acts of revenge and self-defense which included the murder of J.

Do you know how huge and complex an engine would be to generate an OPR of 100???

The largest turbofan (the GE90-115B as used on the 777-300ER) has an OPR of 42 :p The smaller Trent 900 on the A380 has an OPR of around 39.

That's presuming that H and d are two separate variables rather than Hd just being one variable as itself.

In either case, (hd)^3 would still be correct, whereas hd^3 would only be correct if hd was one variable or h had a certein value (eg: 1).

Besides, in general mathematics it's usual for variables or constants to be assigned a single symbol.
Programming is a more specialised thing as computers really don't care.


Also, I'm uncertein as to how his claim at grammitical correctness (which is obviously flawed) he can reasonably claim to be able to answer a load of questions from random subjects by reading them up.

That's not mathematically sound; that's just stupid.

I consider division; it makes sense to me, that a negative divided by a negative results in a positive.

-4 / -2 = 2 (-2 goes into -4 twice).

We can write division as multiplication of a recipricol: -4 / -2 = -4 x -1/2 = 2
Probably not the best way of thinking about it, but it does for me.

I think if you consider multiplication as an extension of addition, it works out (and is probably more mathematical). But I'm too tired to consider that right now.

Yes, actually. The air scatters the light, but scatters short-wavelength light more than long-wavelength light. As blue is the colour of the shortest wavelength of visible light, thus meaning that blue is the colour seen when looking up in the sky, but not when looking up at the sun.

Question: how many hairs are there on your head. Exactly.

Plasma
11 Jul 2008, 10:39
But what if it's red?
That's because at sunrise/sunset, the sun is near-tangential to the point you're looking at. This means light from the sun has to travel a much longer distance through the atmosphere to reach the point in the sky you're looking at. Because of this, much of the short-wavelength light has already been scattered, leaving only the longer wavelengths, such as red, left.
