i got carried away teaching myself, but then the vectors and integration got me so i stopped

thou art strange.
why have I seen this before? By the way, for some reason, I left as dx/dy . If I'd gone on and dy/dx'd it and then replaced x, I would have gotten it!

Spoiler:
Show
I hate being wrong
5. I'm gonna make love to this C3 exam.

6. if i go through all the past papers, solomon and practice papers for trig, do you think i will be able to do the one in the exam?

i am so bad at it xxx
7. So slightly off-topic.. did everyone get the offers they want
8. C2 was hard, though I did better in it than in C1, which I got an 80 in lol.

when the questions ask these stuff, u simply use a rule, one rule --> DEnominators must not equal to zero so in this case 2x+1 must not equal to zero so x must not equal to -1/2 so x=-1/2 is an asymptote
this is the DOMAIN
to find the range, just find the inverse of the function, and use the same rule. Simple as that.

ok not that simple maybe
I feel I'm gonna mess up tomorrow. I really feel extremely nervous
so how would you know if the domain is more or less than -0.5

you should be fine. i think you're panicking. Do you know what part of trig you usually mess up on?

I got all my UK offers (minus Oxford) and now I'm just waiting for the US and Canada and you? I can't read, congratulations with your offers!

I loved C2. (proof yet again, of me being weird) I did a LOT better in C2 than C1.

just try at a point when x > -0.5
TRIAL AND ERROR
this might take a while though
12. C3 is depressing me I cannot afford to fail it. :'(

What SAT score did you get?

I have to do some mixed exercises from the C3 book, go through some Solomon papers and I will relax.

Where does the final part of this come from? the : bit.

2060. I didn't do a retake because I was not going to sit through 6 hours of that ever again. That and 2060's good enough (seeing that most people I know don't get above 2000) you?

How exciting. I have history to do. I might do maths before I sleep.

Pythagoras, draw yourself a rightangled triangle. basically, the angle is y. And as cosy= x, and cos is adjacent /hypotenuse. The 'x' is the adjacent side and '1' therefore is the hypotenuse. Sine(opposite/hypotenuse) would be (sqrt of 12-x2)

since we want it in terms of x. hoped that made sense.

1910. TOTALLY messed up CR. I actually have to retake the SAT this Saturday... I'm so scared ;_; I don't think my vocab and critical reading skills improved
