It is a mathematical term. Do you like Surds (http://www.mathsrevision.net/alevel/pages.php?page=40)? can you understand them?
I had a Maths exam today, and the most eviliest Surds questioned was waiting for me at the end of the paper. It was the Surface area of something, so width x height x depth, and you had to leave your answer as a√2 with a being an interger. It was bloody awful.
I had √2 x √4 x √1/2. It was the fraction that threw me.
an example of Surds:
(1 + √3) × (2 - √8)
= 2 - √8 + 2√3 - √24
= 2 - 2√2 + 2√3 - 2√6
Ever get left nasty exam questions at the end of the paper? or any nasty ones at all?
Another nasty one was doing forumulas ;_;
P = kh or something like that. One of those came up too :(

Does math make you happy? It should, but it looks like it doesn't.

I think we call 'em radicals. They're okay. Not something I was too fond of during my first unit of math this year.

Ohh, you meant Radicals. Also known as x (number) root.
Yes, I do. They are among the easiest numbers to manipulate.

Thats the thing, I DID find Surds easy, maybe its the way exams word them, but that question totally threw me.

I used to love surds, I found them nice and easy. :D :D :D I think they leave the nasty ones until the end all the time, I can't really recall any of the exam questions I've had.....I tend to repress the whole exam experience...I'm sure there were a few in AS maths though.
Smile and Be happy :love:

Math makes me happy. I regularly square root my polygon.

Oh THAT'S what a radical is!
I thought it was some kind of random thing that doesn't exist in our curriculums, but it's surds :lol:
I like them okay. They're easy.

It would appear that Surd is a European name. The only thing I've ever heard is "Radical."

Just wait until you do complex numbers. You'll be missing surds then :p

The current section my Calculus class is doing involves intergrating square roots of crazy functions.
Just goes to show that it always gets harder!

Not really. Radicals also show up in Polar coordinates, as well as Imaginary.

Thank you, professor Bunny, for that insightful and wonderous revelation.

I have noticed an increased amount of sand in your vagina lately, Tavrobel. Want to talk about it?

When EoFF stops being boring and I can stop acting like a huge jackass, I will.
