CSSA MX2 Trial (2 Viewers)

The final question would be walking you through proof #3 in http://empslocal.ex.ac.uk/people/staff/rjchapma/etc/zeta2.pdf I presume.

sort of similar.

The 'basel' element was only in the final 2 marks. in fact, parts i - v all culminated in the result in part v. You could do part vi independently (using only the result from (v))

Why is Basel Problem so common in MX2 exams?

They've used the living shit out of it.

Because it's the first p-series to converge.

And just to clarify, people usually associate p-series to integer exponents, but they converge for any p > 1.

Overall the paper was straighforward up until the last question. Q1-15 were generic textbook stuff (bar 1 question which required a bit of thinking but was only worth 2 marks and wasn't hard when you worked out what you were doing - i.e. finding coordinates of C ). Last question was mostly tedious more than anything else.

the sigma notation thing seemed to be much messier than the expression in this document but. also the reduction formula was one of the harder ones i have seen.

this was the multiple choice question people are talking about. it said in how many ways can 5 letters be chosen from the word ARRANGE. what is the answer?.

I KNEW IT.

I really hope someone from the BOS Meat (Winter one) had the CSSA as their paper for MX2. I bashed those questions into them pretty hard.

Yea MC was bullshit as. Had to do a lot of work for 1 lousy mark. Yea for the ARRANGE question one, I got 21 but I thought it was just too easy so I tossed up between 9 or 12.

Yeah, I think the 21 one was wrong because it didn't factor in the factor there were two R's, therefore the would be less combinations (I think).

Look, I'm not the biggest fan of multiple choice. And you might be. But that's what I felt.

nah i aint either- just curious as to which questions u reckon were tricky

can someone answer that probability question i posted earlier. in how many ways can you arrange 5 letters chosen from the word ARRANGE.

7! / 2!^2

 

[RealiseNothing]

7! / 2!^2

No, you want to choose only 5 letters, not all 7.

 

[Johnstan]

i got 30 for my answer... any1 confirm?

i put 21 .. but im sure it was wrong, people said they put 12 cause 21 was too simple. idk

 

[RealiseNothing]

It's 12.

 

[maths lover]

It's 12.

idk but 10 wasn't an answer. i think there was 9,12,21 and 30.

 

[RealiseNothing]

It's definately 12.

 

[maths lover]

did you just count it or can you show working?.
