Re: Wow, fuck that

you're pretty cocky dude. 74/84 isn't even that good for anyone who considers themselves good at maths
I said ANYONE , that includes getting someone as hopeless as MrBrightside a mark of 74/84.

Obviously if they were smarter then the gauranteed mark would be higher. That is just a lower bound XD

Re: Wow, fuck that LOL THE TITLE CHANGED AND I AM SLIGHTY AMUSED

I lost around 37 marks not including silly mistakes.
Man what a waste of time. I guess MX1 helps with 2U skills..

Am i the only one that get p=2 at the last bit in 6? i know it's wrong
I almost did. I think you must have screwed up your plus/minus signs somewhere.

WHAT THE FUCK WAS THAT EXAM. fuck you bos

I think that's what I got! I vaguely remember dl/dt (or whatever it was) being -10(pi^2)l^2 or something.
$\bg_white V=\frac{\pi }{3}(h^3-l^3)\newline dV=\frac{\pi }{3}(-3l^2)dl\newline \frac{dV}{dl}\cdot \frac{dl}{dt} = -10\pi l^2\newline l=2\newline \frac{dV}{dt}=-40\pi$

someone confirm that just in case.

lol it even says in the question 0<p<1 because it's binomial probability

i proved (ii) by putting P1/P2 and proving that it must be greater than one because if it was less than (p+1)^2 < 0, which means that P1>P2

for the second bit I got p = 0.36. It came down at a quadratic and you had to choose the value which satisfied 0<p<1

yeah that's what i got but it's wrong cause 0<p<1

idk what i did wrong...

I got that. How do you do the next part?

Re: Wow, fuck that

if they don't give carry answers I'm fucked for both 3U and 4U. So I am hoping they do as well (I assume so...anyone know any senior markers?)
They allow carry on mistake

Re: holy fucking shit i might as well just die now.

The most annoying thing can ever happen after an exam is you can't remember your answers to compare to other people alfasdlkfjasldkjfljl!!!!!!
I found this test much more difficult than previous years and the trials
