    PS Mel I hope you feel better soon.

  • Mel A

    I’ll be fine… I feel like I’ve got the normal winter coldy/flu thing. *sigh* You know up until this year I could count the number of days I’d had off on my fingers but this year I’ve been really ill… It’s actually really boring!

    Only 10 online now…

  • Mrs Tibble

    Snuggle down under the duvet and sleep it off! Enjoy not having to go out in the wind and rain :-)
    I recommend lots of cups of tea and Tesco chocolate ginger biscuits!!!!

  • Emma Kitley

    My advice exactly Mrs Tibble!!!

    Oh my goodness I cannot believe that I missed the 13 people online!! But there are 11 at the moment… which is still amazing! :-D

    Lots and lots and lots of love Mel xxxxx

    I know it’s late but could anyone please help me with this:

    There is a gradient of 1/2 and point (3, -1)… finding the equation of the line, giving answer in the form ax + by + c:

    y – y1 = m(x – x1)

    y + 1 = 1/2(x – 3)

    and from there I get:

    x – 2y – 1 = 0

    but the mark scheme gives

    x – 2y – 5 = 0

    What am I doing wrong?! :(

  • Mrs Tibble

    Change side, change sign with the 2.

  • Emma Kitley

    I don’t understand, what 2?

  • Mrs Tibble

    y + 1 = 1/2(x – 3) is correct.

    Multiply LHS by 2 to get rid of the half.

    2y + 2 = x – 3

    x – 2y – 3 – 2 = 0

    x – 2y – 5 = 0

  • Emma Kitley

    Oh right… thanks. Sorry I’m getting so worked about about this exam! I’m making stupid mistakes and the more papers I seem to do, the worse I seem to do :( Will scrabble you back shortly :)

  • Mrs Tibble

    Sounds like it’s time for a cuppa then!! Don’t do any more papers tonight – it will be counter-productive.

  • Mel A

    HOW DID IT GO!? I’m so sorry not to have been around to give encouragement, but I hope it was all fantastic like the fantastic people you are, and DO NOT worry about it. I know what you’re like! Just take a deep breath and focus on the next exam! And you’ll do fine! And I’ll see you soon- Friday if not tomorrow :)

  • Emma Kitley

    I thought it was good :-)

    Though I’m stressing about mechanics now :(

  • Fiona

    i thought it went well also, and am also a bit worried about mechanics if i am to be honest

  • Mrs Tibble

    Glad it went OK. When is M1?

    Take care Mel. Don’t come back too soon.

  • Emma Kitley

    Friday, alongside our two physics modules :( Nice jam packed day!

  • Emma Kitley

    *Friday in the morning

  • Fiona

    umm are there any M1 papers posted anywhere???

    i’ve done all mine and just want to do one more b4 2morrow

    danka

  • Fiona

    Actually ignore that i found them online

  • Emma Kitley

    Hi Mrs Tibble, I was just wondering if we had any Decision homework due for tomorrow? Sorry, it’s just been so long since we had our lesson I can’t for the life of me remember :-(
    Hope you’re having a good weekend :-)

  • Mrs Tibble

    It’s a good job you asked that – I hadn’t even realised there was a lesson tomorrow!!!! Cos it’s whole school on exams, I forgot you lot were coming in. Will everyone be there because the next lesson is important for critical path analysis.

  • Mrs Tibble

    Oops – didn’t answer the question! The only possible homework was finish 5A if you didn’t do it in class.

  • Emma Kitley

    Gosh I’m not sure actually, I know that Fiona and I will definitely be in because all of our resits are over… but I’m not sure about the others… Sorry, that wasn’t helpful at all!!

  • Mrs Tibble

    Any chance of texting the others to find out?

  • Fiona

    Mel will be in cos her sociology(sp) isn’t until a wendnesday…i don’t know which one tho.

    I have no idea about india or lojana and have no way of contacting either of them…sorry

  • Mrs Tibble

    OK Thanks

  • Emma Kitley

    Yeah I don’t have either Lojana or India’s number sorry :(

  • Mel A

    Can I just point out, however irrelevant it now is, that my sociology exam is first thing on monday morning- nothing to do with wednesday at all :)
    Hmm hmm… Oh and Em I borrowed your book in my free so don’t stress about doing it… And I shall turn my room upside down (and check under my bed!) as soon as I have a spare moment… Have a lovely evening all!

    A group of scientists conduct an experiment on 3 students. They lock them each in an empty room on their own for 24 hours with nothing but a pen, some paper, and a tin of food (but no tin opener).
    In the first room is a Chemistry student. After the 24 hours, the scientists examine his room. They find that he has eaten the contents of the tin, and he tells them that he threw the tin against the wall repeatedly until it cracked open.
    In the second room is a Physics student. When they examine his room, again, they find the contents of the tin eaten. However, the paper is covered with reams and reams of calculations. The student tells them that he worked out exactly how to throw the tin against the wall so that it would crack open first time, and succeeded.
    In the third room is a Maths student. However, when the scientists examine the room, there is no sign of him. The paper is, as with the Physics student, covered in calculations. But the scientists suddenly realise that strange sounds are coming from inside the tin. They immediately open it, and the Mathematician crawls out, saying: “Gosh! I got a sign wrong!”

  • Mrs Tibble

    !!!!!!!!!!!!! :-)

  • Emma Kitley

    Lol! Is that a good ‘!!!!!!!!!!!!’ or a bad ‘!!!!!!!!!!!!’?? :-D

  • Emma Kitley

    Ok try this:

    Person 1: What’s the integral of 1/cabin?
    Person 2: A natural log cabin.
    Person 1: No, a houseboat – you forgot to add the c!

  • Emma Kitley

    (I have to admit I’ve found these on The Student Room!!!) But I think that last one was so funny!!

  • Emma Kitley

    Last one I promise!!

    sinx, cosx and e^x go into a bar, sin and cos are having a right laugh,
    but e^x is just sitting in the corner. cos asks him, why dont u integrate like us? e^x says, it wouldnt make a difference

  • Emma Kitley

    Mrs Tibble could you please just remind me what questions you wanted us to do for homework? Sorry emma’s head = an unorganised sieve :-(

  • Mrs Tibble

    What does an organised sieve look like?!!

    Finish 5C then do 5D which is a continuation of the 5C questions.

    Have you seen there’s no more Scrabulous? :-( (

  • Emma Kitley

    Gosh! I read about that in the papers the other day… but I presumed that they were only talking about scrapping the facebook version because facebook were breaching the copyright!! I didn’t realise that Scrabulous was being removed completely! Mrs Tibble!! What are we going to do :(

  • Mrs Tibble

    You’ll have to do some knitting – or get back to your family tree! Or even …… more maths lol!

  • Emma Kitley

    Oh yeah, my family tree! I forgot about that! But I really enjoyed playing scrabble :( Is it definitely going? And when? We’ll have to squeeze as many games in as possible until then!

  • Emma Kitley

    Mrs Tibble, I have plotted my giraffe (Geoff the Giraffe) and have coloured him in! :-D
    Took me ages last night! Will you please put him on your wall? :-D
    Hope you are having fun at school today ;-)

  • Mrs Tibble

    lol!!

    Don’t we always have fun at school?? ;-)

    Would you like Geoffrey laminated?

  • Mrs Tibble

    PS The walls are now finished :-)

    and Mr Atkins has eaten all the chocolate gingers :-(

  • Emma Kitley

    The walls? As in putting up work on the walls in the classroom? Or the walls you painted in your office lol? :-/

    Yes of course we have fun at school… it’s just that I was glad of the lie in this morning ;-)

    Yes please, preserved forever between two sheets of plastic :-D

    Hmm how did Mr Atkins get hold of the biscuit barrell?! :-(

  • Fiona

    okay so i no TECHNICALLY this isn’t maths

    but if i have 1.58 = 1/sinC

    how do i find c??

  • Mrs Tibble

    sinC = 1/1.58

    C = sin^-1 1/1.58

  • Fiona

    and again i no this isn’t maths, but i’m getting 0.68 as a critical angle :S

    (btw if physics had one of these i wouldn’t ask u my physics questions online)

  • Mrs Tibble

    Maths and physics are inseparable, Fiona!!

    And I guessed it was refraction – aren’t I clever?!!

    Try taking your calculator out of radian mode!!! It needs to be in degrees for physics. Then you’ll get 39.3 degrees.

  • Fiona

    haha, i so didn’t notice it was in radians

    that makes so much sense

    thank you :)

  • Mrs Tibble

    PS It would be O.69 radians too if you had rounded correctly!!!

  • Emma Kitley

    I’m really stuck on binomial expansions, I know this is probably so stupid but no matter what I try I don’t get anywhere near the answers in the back of the book… I don’t seem to have mastered even just the basic principle of it…

    For instance,

    (4 + 2x) ^ (1/2)

    = 2 (1 + x/2) ^ (1/2)

    = 2 [1 + x/2 – 0.25 (x^2/16) + 0.375 (x^3/64)

    But I’ve done something really wrong I know because the answer in the back of the book just gives

    = 2 + x/2 – x^2/16 + x^3/64
    :-(
