Are you good at Maths?

[Damocles]

But...

I have imagined that Damocles is a British Sheldon Cooper for some time now...

Hardly, Sheldon doesn't get things wrong.

I'm offended at your suggestion that my math problems are inaccurate.

 

[Irwell]

Not quite. Sheldon doesn't think he gets things wrong.

;-)

He only gets them wrong when they don't have an answer that can be defined scientifically. Even then, Schrodinger's cat as a dating concept was genius.

No.

x.y and z are co-ordinates of the object that uses them. There's a difference

You would be a systems engineering customer from hell and I've worked with a few.

Disagree.

Missle A needs a co-ord system. You will be greatful of an xyz axis rather than ijk

Vectors have different attributes to Co-ordinates and you'd be bringing a print out like this to a review meeting.

You appear to have stumbled into a British discussion. Please respect our customs and spellings.

WE seemed to have crossed wires. My idea is that everything has a representation in cartesian systems.

Your docs agree with this but go a bit mad notationally<br /><br />-- Sat Jan 12, 2013 1:30 am --<br /><br />

It allos you to use every piece of technology. From your chair to the internet

Start at the North Pole, head south along the Greenwich meridian until you get to the equator, head west until you get to 90 degrees west and then head back to the North Pole. You've described a triangle the angles of which add up to 270 degrees. non Euclidian geometry rocks!

I always thought vectors were the distance travelled and the co ordinates determined the direction. so a Co-ordinate would appear as (x,y,z) whereas a vector would be (0,0,0) to (x,y,z)

Could be wrong but to me co-ordinates locate an object, vectors give magnitude and direction?

Correct!

They're also different to scalar variables. e.g. Mass(scalar) versus Force (Vector).
