(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

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.

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:

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.

Yes.

... 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.

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.
