i don't knw there may be slight varations, because u will get a negative value when u do the subtractions, in the last part u have to take logs on both sides to determine the greatest value, so there is a chance u may have made a mistake, what value did u get?.....

when i took logs i changed the sign as log0.75 is negative.
n> 3.4
i had n is atleast 4

hey guys... how many marks do you think I'll lose for integrating between the wrong limits?... i got the coordinates right after the second time but I forgot to integrate the darn thing again between the new limits....

will anyone upload the paper?

I think I did pretty well. There were 4 solutions to the tan^2 one btw, and the Trapezium rule was around 150-ish.

Oooh this is encouraging, the answers people are giving on here seem familiar! :biggrin:

Perhaps we shoudn't discuss the questions too much yet, I think people who do Edexcel overseas get the paper on a different day. Correct me if I'm wrong though!

All in all, it was a nice straightforward paper I thought. It's all good :smile:

C2 resit down, C3 and D1 resits to go. Oh and C4 and M2 first attempts lol. w00t.

i got 154 for the trapezium rule. Still gutted that i missed ±2 for the tan question. Everything else went really good.

Reply 67

yeah i just worked out the trapezium rule question from memory (it was root of 1.2^t-1) and I got 154m as well.... Im sure Im using the same method as I did in the exam as well.... weird.....

I got four solutions as well, but two of them don't fit in the range 0<=x=>360, so theres only two solutions.

Just to make sure you know, <= means greater than or equal to. I don't know how to do the actual sign on computer.

Why do u have to times by 2.5?

everything in hte brackets....

the question was the graph of root (1.2^t-1) between the limits of 30 and 0.... i've just redone it and got 154m yet in the exam i got 200.... (annoying) i checked it so many times i must have made a mistake in filling out the table.... will they use error carried forward do you reckon?

Wouldn't you agree that the exam was much much much easier than last year? I am well gutted, coz I didn't revise, and I messed up an easy paper.

Ahh dammit i think i got the tapezium rule question wrong too! I seem to remember mutiplying 2.5 and 90 something in the last step! There goes any chance of getting 100. :frown:

EDIT
actually it might have been a mistake filling out the table, i think i got 15.something for the last value we needed to work out? ah well. :frown:

Reply 77

It was supposed to be 1/2 x 5 x [ 0+15.73+2(3.71..+...)] which gave 153.99.
