Cost: €60 euro per student (this covers all eight lectures abd a seminar booklet each day) Write to: George Humphrey, 9 Kincora Drive, Clontarf, Dublin 3 or Phone 01-8335906 or 0879787380

Cheques etc. are to be made payable to Brendan Guildea

A Stamped Self Addresses Envelope should be included with the Cheque so that tickets can be forwarded on to you.

Sounds like a cool idea.

And heh, I looked at it and went "What?! We never learned this 'registration' thing!". Yes. Talented. Is what I am.

Piste

*slow claps*


Really, REALLY slowly.

The line???? Whats that? Is it like the equation and slope and all that, or am I gonna fail because of not knowing?

David19

Yes its the equation of a line and the slope etc. Its called coordinate geometry of the line.

Piste

"The Line" is one particular line you study for Junior Cert. It's a unique line in that it's 3D, you must learn all of its properties as well as the formulas (they're REALLY long) to find its volume and area too.

PurpleFistMixer

Stop misleading people, Piste!

The line is 4D.*



*is not true. OR IS IT?!

Aisling(",)

I would do it because im going to end up failing maths but I've just started grunds and doubt my ma would pay for both

Boooo urns. Not fair.

3D lines do exist in the form of 2x+3y+4z=5, but they aren't even on the LC, I don't think. However lines don't have areas or volumes, you would need 2 or more lines for that.

Piste

If it's 3D wouldn't it HAVE TO (by law like) have a volume, if not an area?

A fine point here but not necessarily. Imagine a twisty drinking straw. Now imagine a really really thin one, so thin that it is 0mm (i.e. nothing) across. Its a 3D object, but has no volume.

I have to admit I haven't studied 3D lines, but I suppose these people could help.

oooh you have chuckie piste? I had him for LC last year. I also went to the seminar in question when i was not doing so well in the junior cert. It was very helpful, I advise people who are struggling to go to this.

Piste

Chuckie? Whonow?

Piste Confused, self destruct in 5...4...3...2...1


*KABOOM*

Victor: If you put said drinking straw into a full container of water you'd displace *some* water, and therefore it's have volume.

Victor

Tee hee hee

Remember this is a really really thin straw, not so much a straw as a really, really thin wire that has no width....

Remember

volume = length x width x height
width = 0
=> volume = 0

BY LAW!!!!!

[edit] you can have lines with volumes, but we call these tubes, cylinders, pipes, cuboids, etc.

chuckie is brenden guildea the guy the cheque is made payable, i only realised after i posted that george humphrey's name was there too, so that's your teacher, nevermind

Victor

2D lines http://www.americanapparel.net/storefront/stuffthis/images/rsac301.jpg

Some samples of 3D lines

PurpleFistMixer

Ah, but a 3D line with no width surely couldn't exist in a 3D world?
While existing in three dimensions, it's impossible to create something which is missing one of them. I mean, you can create representations in the form of a line on a page, but even that supposedly 2d line has three dimensions, really.

So, you can draw a 3d line in the respect that it's a 2d shape moving through three dimensions, but it can't exist truly.

I most likely make little sense. And this is why I will never be a good teacher.

Revision? For the JC? =/

PurpleFistMixer

Yes, that's a wonderful observation there.
This thread IS about Revision, and it IS in the Junior Cert forum.

If you're about to make some crack about "OH EM GEE YOU DON'T STUDY FOR THE JC WHY DON'T YOU TRY DOING SOME REAL EXAMS", then, just... don't. We've heard it before. If you think you've got a valid argument and you want to debate it, or something, start a new thread.=)

Remember that line on the page is merely a representation of the line, it isn't the actual line.

Now stop arguing, go to the Gulf of Guinea and find the equator (pictures required).

Piste

The Equator's a Lion, not a line, why do you think it runs through Africa and all those hot countries?


Yeah like PFM said, if The Line is missing two dimensions it can't exist in a 3D world, it's ompossible to have a 3D shape with two of the values as 0.

I was given that! Sure is a long time but at least we get a long lunch!!
