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.

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.
