in fact im sure you will do more than fine. you always do well : )
good luck! x x x
Luckily it's Sociology. And the easiest module of the 3.
I am on a Sociology website!
well good luck then.
Did a past paper and got 43/50
Is it wrong that I'm considering applying for medicine, a subject which I have have never had any interest in before, purely because I want to be like House?
That's the best reason to do it ever!
I got 100% in every single pure module at a-level first time.
differentiation, integration, logarithms, wave function, "further trig", vectors and all that jazz
Whats the answer to this: A line of equation y=2x is tangent to a circle with centre (t,0) and radius 2 units. Find the value of t.
I imagine you need to sub the equation of the line into the equation of the circle, then use the discriminant(b^2-4ac=0) to work out "t", but all these letters are confusing me.
That's right, if you sub the line equation into the circle equation, you get a quadratic equation for t. You just need to use b=2t, a=5, c=t^2-4.
Isnt the equation after subbing in the line
where from there?
Compare it with ax^2 + bx + c = 0 to get the coefficients a,b,c, plug them into the discriminant.
Or -root5. That's how they catch you out.
± root 5
Though in the question theres a diagram and the point (t,0) is in the positive direction of the x axis, so I dunno.
That's no excuse, unless it explicitly says either the solution is positive, or there's only one solution.
is y=2x the circle must be in the positive direction of the x axis?
No. It seems fairly obvious to me that there are at least two solutions, although the second one is not necessarily negative.
Frankly, the setup just seems to be a fancy way of saying "solve these simultaneous equations" - just remember that it's maths, not physics, so there are no unphysical solutions, and not giving one of them is a good way to drop an easy point.
I have no idea how that works. how can a line perpendicular to y = 2x not pass through the x axis in the positive direction? far out.
I was wrong because I was forgetting the the circle has radius 2. That'll learn you for listening to me.
I stand by my point that it's worth stating that there are two solutions, though.
If you care any more, here's a diagram.
I am completely failing this exam tomorrow. I am ridiculously upset right now.
as your face!
I am really worried about this damn exam but I just can't study. I don't remember anything, even though I spend half my time studying for it!
I have my first tomorrow as well. Sociology - Methods. Easy, but I don't really want to do it.
I don't like that board. They don't post out results.
I like them. They post the mark schemes on their website from previous exams. Really helpful.
To be honest I'm alot more worried about the Poverty paper. I can't remember anything of what we've been taught. :s
I did Education, and Family And Households.
One june 11th
I got my history coursework back today and had full marks and now feel worryingly complacent :(
recommend me something to listen to, on the bus to school.
Something calming probably, but yeah:
And have a rap battle during the exam.
Here's a pencil
Go home, write some shit, make it suspenseful...
What an ingenious rhyme.
