## no it doesn't

sin (pi/6) = 1/2

that's trigOWNEDmetry

## Well done

Next question.

Tan 90 = ?

## cos sin is shit?

## thats a sin cos her tan is fake

was the correct answer

## in GYBE! terms:

oo

## nope

it's undefined isn't it?

## or

-1.99520041

## Undefined

technically its impossible. Its not infinite cos even if the sides continued infinitly out they wouldent reach each other.

## and it's defined as

sin/cos, and cos 90 = 0, and dividing by zero is undefined. omgmathsissomuchfun

## erm

"even if the sides continued infinitely out they wouldn't reach each other"

well yeah - they would. thats like saying an exponential decay never reaches 0, but if you carry it on infinitely it does.

its a weird concept, but thats infinity for you

## they wouldn't

at no point do the lines get any closer.

## wait

what lines are we talking about?

i'm talking about the asymuthal at 90 degrees and the tan(x) curve.

## *asymptote

## a triangle

where two of the internal angles are 90 degrees.

## oh sin90/cos90

sure

but if you look at the standard tan(x) graph then you should see what i mean

i don't know why i am taking maths lessons from someone who hasn't even got a fucking GCSE anyway, seeing as i'm in my final year of a very maths-orientated Physics degree :P

## (yes_ , not jp100)

## i have GCSEs

and A levels, get me.

## and a Maths degree soon

hopefully

## of course ive not got a GCSE

I dont live in england, dufus.

And as for your physics degree, good for you! But I know what a basic tan x graph looks like. As I said below, it theoretically extends to infinity, you agree, right?

So theoretically, it reaches infinity at tan 90, right? Ok.

Now explain infinity to me. I guarantee there will be a million other people with a million other definitions other than what your professor told you. Really, If you can find an exact definition of infinity backed up with evidence, statistics, facts, etc, I will give you a gold star.

## well you said earlier

"Its not infinite cos even if the sides continued infinitly out they wouldent reach each other" so maybe you are just a bit confused. its understandable - our brains just aren't equiped to think about concepts like infinity and understand them at all.

and no - i don't have some definition a professor gave me, but dictionary.com provides me with "A space, extent of time, or quantity that has no limit" which is nice and catchy.

and what is this 'evidence, statistics, facts etc' you want me to provide? statistics confirming the existence of infinity???

anyway, don't worry yourself with such philosophical issues, best to stick with revising for your scottish (?) GCSE equivalent for now :)

## cop out^

Agree to disagree etc etc

Anyway, thanks for advice. I'll stick with my ickle wickle Scottish GCES for just now. Maybe if I try hard enough they'll bump me up to the Red group and I'll get 10 minutes extra play time! Give me a call once you get your degree, and we can continue to discuss probably the most boring subject in the history of the universe :)

## cop out?

i gave you a definition! what the fuck did you want? my thesis proving the non-existence of infinity as a concept, backed up with 'statistics' and some 'facts' to prove it?

i don't think DiS would be my first port of call if i had such a thesis to be honest!

anyway. erm i'm sorry to say i probably won't be calling you anytime soon. i'd rather not try and explain the unexplainable to a scottish schoolboy in my spare time kthxbye

## ...

"i don't think DiS would be my first port of call if i had such a thesis to be honest!"

Exactly, so shhhhh, yeah?

## dude, you're trying, transparently, to get people to do your homework for you by phrasing it first e

despite the fact that it's working, you are in no position to get uppity.

## ignore everything after 'you'

on reflection, it would have been pithier that way anyway

## depends on your definition of infinity

and how you interpret it.

## 90° or 90 rad ?

## maths

at this hour !

NO WAY !

## I have written exact values all over my calculator

because I cannot remember them at all :(

WHAT AM I GONNA DO IN THE NON-CALC PAPER, MANNN?

## no trig?

## Exact values are not related to trig

as far as I know.

## Yeah they are!

Havnt you been taught the method thing? Its the only way I can remember.

To get get 60,90 and 30 you take an equilateral triangle of side 2, and cut it in half, giving you a right angled triangle of sides 2 for the hypotenuse, 1 for the base, and root 3 for the height.

to get the other angles you get a square of side one and cut it diagonally to give you sides 1 and 1 for base and height, and route 2 for the hypotenuese.

Woah

## Nope :(

And I need written examples and diagrams, so you're help is no good.

It's all my teacher's fault.

She gave us the table and said "learn it -chuckle-"

I hate that bitch.

## oh god

All i can say is good luck then

Im going past papers right now. Just scraped a pass in my prelim. Uh oh.

## I got 26%.

And she refuses to help me because apparently I "have an attitude" towards her.

I hate that bitch.

Does bitesize have stuff to do with that method? 'Cause I am like majorly scrwed. I will be very embarassed with myself if I don't pass bloody maths.

## I think it does.

Worth a look anyway. But then theres all that ASTC shite to remember. ARG

## im on the english bitesize

giving my high pitched tips on grammar.

true story

## This thread

makes my head hurt.

## THE LIMIT DOES NOT EXIST!

\m/ MATHLETES \m/

god I love mean girls.

## and freaks and geeks!

'you're our best mathlete!'

## Trigonometry = piss easy.

Isn't there a Mr Bean sketch where he takes a Trigonometry paper?

## As sad as this sounds

I miss maths. I was good at it.
