    Simultaneous Equations ........

    x+y = 5
    x^2 + 3y^2 = 49

    :eek:

    Okay look at the mark scheme :p: I've got it. x=5-y. Substitute that into 2nd equation.
    Thats what I did in paper 1

    Ohhh gosh...I have this exam tomorrow too..AQA...doing modular so the percentages and interest stuff isn't on my paper but I'm kinda scared...I hope it's not as hard as the last paper I never seem to do very well in maths exams, I got a C and a B on my early modules :confused: and I think an A in each of the two coursework pieces....I've given up hoping for high grades now, just want to pass the flipping subject so I never have to do it again! lol!

    Fingers crossed for it anyway....good luck everyone!

    Btw, simultaneous equations, bearings, trig, graphs of sin cos and tan, shape areas/volumes? Anything else which is likely to come up tomorrow? Anyone know?

    Thanks,

    You don't need to know the graphs of sin/cos/tan, you can work them out on your calculator.

    thanks a lot lol, I am sooo silly :rolleyes:

    Paper 1 was like...death...lol...I so hope this one is easier or I will actually cry :p: I almost did in paper 1, the only marks I was sure of were most of the first page or two, the circle theorems, half of the cylinder question and I *think* the last page with the graphs...everything else was just guesswork...

    *prays for the calc paper to be better*

    Good luck guys!

    Graphs of the f(x) and knowing how, for example, changing it to f(-x)+3 changes its appearance. There was a thread earlier about that.

    There's nothing to worry about. Just a few very basic rules to learn. I'll have a look for a good explanation of it in a minute for you, if you like.

    That might help. f(x) just means the examiners don't have to write the actual equation of the line for you. It's just there for you and them to modify, to save writing it all out.

    Thankyou! I can do the moving it up and down the line and then along the line, its just the strectching and squashing part I need to learn.

    :eek: stretching and squashing? :confused: LOL...oh here comes failure...

    f (x) just means the function of x doesn't it? and you plot the graph with whatever the function is? argh why am I doing higher tier!
