Oh yeah.

I think I ended up with 30.

Anyone else get 35 for trapezoidal rule

We posted at the same time basically. I'm glad I'm not the only one who got around that number, but I don't know whether it's right or not. I'm doubtful it is, seems too small.

i got 90 for the trapezodial rule

Not really when u half the 70

JustForClarity

The trapezoidal rule answers seem to be all over the place, I wonder which one of us is right!

NellyDean

I got 35 too!

stephenjmcd

When u do it out u get 70 then last step is half ur answer = 35

Great paper, had no problems with it, all questions very doable, only one part of q's 8 or 9, I can't remember which. I literally lol'd when I saw that question where you had to write down the fractions to 2 decimals point and plot it on a number line. Delighted with that, no tricks, a very fair paper!

35 is definitely the right answer.

Cool, I must have gotten 35 then, not 30.

OH MY GOD just clicked that .. totally did NOT see q.9



How badly will this **** me over?

Jordan537

i got 35 for the trapezoidal question

Jordan537

did anybody get this question out ? The mean distance from the earth to the sun is 149 597 871 km. Write this number in the
form 10 , n
a where 1 10  a and , n correct to two significant figures.

that question wasn't on the paper. There was a q on speed,height - calculus instead.

shootie

That was easier than expected. Only the final question threw me off but attempted it anyways, high c low b.

ray2012

****e, think I left out the '2' in the formula for the trapezoidal rule How much marks do ye think I'd lose for forgetting the two ? Hardly more than 2/3 ?

1.4x10 to the power of 8.

Q9 wasn't on the paper ??

Lcstudent2013

Wtf???? Was question 9 even on the paper? I didn't see it either?!?

Wow, that worried me. That last question wasn't on the normal OL paper. Think it was on the one that was a different phase or something?

The uploader in the SEC may have uploaded an earlier draft than the final paper.

Oh well, gives an insight into the way they think for questions.

stephenjmcd

That's all over the place, q9 wasn't on it and that q8 was q6

JustForClarity

The version uploaded is an early draft I assume. Although at first glance that Q9 seems fairly nice.

You just had to move the decimal place back 8 places, which makes 1.49597871x10(power) of 8

And it was to 2 significant figures, so it would have been 1.50 x 10 (power of 8) .. no ?

Awh thanks, didn't realise.. just thought I left it out!!


My stomach was growling away so i was kinda rushing myself. Woulda made sense that'd miss a q...


Phew

Chabals Beard

Man that was easy

Jordan537

q9 was on the paper for me.....

The Pheasant

**** me nearly had a heart attack there with that Q9...thought I'd missed it - felt especially stupid because I left early
