Yep, I got that, not that complicated but not very neat either...
Now the general question is only a very slight adaptation on that: take a general triangle with angles x, y and 180-x-y, with base angle theta above the x-axis. What is the product of the gradients of the lines?

I would be expecting it to be in the form or something of that ilk

I get which is not too complicated as a formula
I got something very similar. But slightly different.

my first time using latex so bear with me if there are any mistakes.

When you worked out the angles did you get 60-x and 60+x and x? Thats what I got but tan (60-x) should be - tan (60-x) not +. dont worry I see my mistake it is now.

On the denominator I think you may have done some simplification or something?

My memory may be lacking, but is this not which is a lot better

I think has become somehow for you

I just expanded it and indeed it is but the one you wrote above is for rather than . Deejayy's right, you need a negative sign in your non-expanded one. And Deejayy, I'm not sure why the 60 is still in there.

I got:

Which goes to as you stated.

No the thing I wrote was for : look at the denominator.

is the correct answer- just consider the sign of the product when theta is small.

7. I just got an email from the University of Nottingham asking me for my unit grades . Has this happened to anyone else?

Yeah thanks I remembered the formula incorrectly.

EDIT: Oh the demominator, didn't see lol. Sorry
10. Hmm I wonder why it simplifies to

Edit: By it I mean the product of the three gradients. It seems like there is some argument which would get to the answer without using algebra.

I got an acknowledgement for Imperial G100 yesterday. I haven't heard from Warwick for G100 yet, but my friend, also for G100, got an offer last Thursday
When did you apply and which unis? any offers yet?

Well that's unusual... did you get A in Maths AS?
13. (Original post by TheMagicMan)
This must be wrong. If one side has a gradient of 1. the another side does not have a gradient of 0 as this implies a 45 degree angle

And even so, if one gradient is zero, the the product is zero
Yes sorry. I've just noticed it! Thanks for pointing that out! I will try again!

My application was processed on 4th October. No offers yet

I applied to Cambridge (Emmanuel), Warwick, Imperial, Bristol and Bath. G100 everywhere.

it doesn't matter. You are pretty much guaranteed an offer if your PS is geared towards maths.

I believe last year they gave offers to 93% of applicants. If you are doing doubles maths and a third subject with AAB at AS, you will get an offer.

did you get a B in AS maths?

EDIT: or are you trolling?

Goodluck! are you an intl applicant?

Many domestic applicants have recd Maths offers from Watwick, Bath as of now.

I was wondering if he/she got lower than an A as well.

No I've finished my A-levels - I'm on a gap year - and received A*A*BB in Maths, Economics, Further Maths and Physics respectively. (In my AS I got AAAA)

I have no offers/rejections... sigh
when did you apply and to which unis?
