Maths Theorems

A193

Hi All!
Im writing up my math theorems again and i dont have the 'given' for my deductions on the circle can theorems!!

Where i find them..or can you tell me,it doesnt matter about the labels i can work out my own off yours..if you post em...thanks!

Me thinks they dont ask the deductions anymore...

Oh God Theorems....the worst invention of man and btw they do still ask deductions

I found that, not sure if it's much use to you or not. Would give you my own theorems but we've only done the name of the theorem and the diagram for the cicle theorems because we ran out of time berfore pres.

the circle deductions do not have a "Given" or "construction". it begins with the title of the deduction, the diagram, To prove, and Proof

TITLE

DIAGRAM

TO PROVE

PROOF


hope this helps:D

I didn't learn all of them. I left out the ones they asked previously, and luckily it worked out perfectly, although we were asked three which I didn't see coming.

On the morning of the maths JC I flicked through the papers and realised two theorems had never been asked, so I learnt them, and both came up *









*not a recommened attitude to studying for maths.

My teacher told us that the theorems were only worth something like 5% and said we should be better off learning something else :S

Grrrrr!!
I hate da way teachers r all so different!!
My teacher is always rantn on bout theorems nd how they r so important, i suppose shes rit as they cud change a c into a b bt still I Hate Theorems!!!
All da triangles r ok bt circle theorems!!?!?!!
:mad:

Ah please use the whole keyboard, it's so much easier to read when people use full words.

But yes, theorems are miserable.
Do honours maths for the LC and you don't have to learn any, unless you want to.

But why are they marked in the book so?

PurpleFistMixer

Which ones are these? I know if you do the Group Theory option you've about 4 theorems to do...
The only ones I can think of are proofs of formulae, but I guess you've to learn them off so they're as good as theorems.. (proof of the cosine rule and all that)

Yeah, there are about two per chapter, i think. Well, that's according to my teacher anyway. In my book, they're marked with a *. That's honours maths for leaving certificate or something. Not text and tests anyway.

Hm, curious. I'm using "Maths" by Aidan Roantree, maybe I've just been missing them. It doesn't feel like there's as many as for JC anyway. No pythagoras or anything.

Therom 10 is to prove pythagoras for honours JC trust me im learning it right now

Were talking about LC honours maths, possibly off topic in the JC forum, but we'll live with it.

I think thats the one were using as well, the first one is blue, second is red? Anyway, generally before each topic they have some proof or other and mark with an asterix, meaning it has to be learned off.

Yeah that's the one. Hmm, I never noticed those things, but thinking back on it (and after having to prove the addition rule in differentiation for homework) I guess there are things to be learned. It doesn't seem as arduous as the theorems for JC, though.

I still dont want to learn them!! I'd muc raather go in and astound with my mathematical skills, not how well I learned something off by heart

PurpleFistMixer

True that, but you don't need to learn them off by heart if you've enough maths skillz. : p

Well, not wanting to be bigheaded or anyhting, but I can't wing it on the theorems at all. I have no idea where to start, but once I kinda half know it, then logic rules and I can get it out.

PurpleFistMixer

Yeah, you just need to remember the trick and most of them are fairly straightforward after that.
