Introduction to Maya - Rendering in Arnold
This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

first thing I've seen in this subject that's possible to understand.
I like the part where the universe imploded

it's clearly obvious that that's not true.... (-x) * (-x) = x^2
but then maybe they just told you guys that to keep things simple
it happens...
that's a "Ch" pronounced as a "K"

My point was that if x is negative, then ((x)^.5)^2) is undefined...

Sorry... I may have made a mistake there??... I meant to say that you can't take the square root of a negative number... no fault of my math teachers...

That 'y' and 'x' are not there purely as arbitrary figures. Even as a symbol, they are used to represent something and are used for a reason. I used to wonder about it too until I begin to see that equations don't exist in isolation.
As in, what's the context? Calculus? Or are you dealing more on geometric equations or are you considering the complex numbers space as well? (What are you trying to prove/disprove?). I'm sorry if it sounds vague, but I had forgotten the actual examples. The above is what my prof advised and explained and it seemed to make sense to me.
But if I recall, the (associative? can't recall) law for powers hold for all integer values for power. If my memory isn't shot, I think it even holds for complex values for power.
All in all, I'd say that you shouldn't worry about it. And if you want a serious answer, approach a maths professor (a non-specialist-maths prof may give an incomplete answer). The average teacher's knowledge of mathematics may not be complete.
Though to be fair, the maths profs I know tend to speak in pig Latin... Maybe you can find one who speaks a language from Earth...

Thanks for the reply,
What I managed to understand so far is that this question is probably not meant to be understood by an 11'th grade student...
Or as my math teacher likes to say whenever she doesn't feel like thinking to much: "That's for when you'll be studying at a university"
Thanks anyway,
Benny

Don't worry about it. It'll make a lot of sense when you're in the higher level of maths. But it'll likely only really make sense if you specialize in mathematics.Originally posted by BennyK

In which case, you'll then be asking... Hey wait a minute, prof you said that "blah blah blah"... But that doesn't really make sense.
To which he'll reply, it'll make much more sense when you do your phd and specialize in "blah blah blah"...
It's a vicious :hug: (but interesting
:blush: :headbang: 
:angery: 
) cycle.Actually, for my friends and me at least, it's so mind boggling that we can't even ask what we don't know. We just have a strange nagging feeling that something is not quite right. I'm always surprised whenever my calculations and proof are actually correct.

Actually, the maths (and only maths) professors in my university are pretty heavy into sports. They play tennis or basketball often in the afternoons despite being quite old.Originally posted by Mayaniac

Heck, they even challenge the students to a profs vs students game of basketball every semester. So I figure they probably will do sports and THEN smoke a pipe if something doesn't make sense.
ACTUAL ANECDOTE: Professor Andrew Wiles solved the Fermat's Last Theorem in 1995. Read his ordeal if you're interested. What a top notch professor did when something doesn't make sense to him. (I think he all but locked himself up in the house to work on the problem until it is solved.)

I believe that's what Einstein used to do... I remember seeing a biography a couple of years ago. Nothing new then.Originally posted by Darkover
