Easiest paper of my life but also why was there so much integration

Unironically hardest paper I've ever seen, thought they accidentally gave me a Further paper or something. Don't think I did too badly, but objectively those questions are more difficult than all the past papers, so silver lining the grade boundaries should fall.

if you found it easy then you are an absolute fucking genius. even the a* students found it difficult

yeah id like to know what "easy" means, I got 95/100 on my last mock and I think I might have barely broken ~80 on this one

I'm usually quite good at getting like 55% so if the boundaries are lower this year that's good for me I thought question 1-9 were free

To be honest I thought questions 7/9 were some of the most difficult mid-paper questions they've ever released, and then the last 4/5 questions were also more difficult than normal

yeah the first few questions were somewhat reasonable except the circle one then you had the geometric series question, the proof question and the last differentiation question just to name a few

Tbf my teachers held a maths revision thing right before and since I need a B I've been nonstop revising for the past 3 weeks so maybe I'm just more locked in than usual and the paper actually was really hard

The question about kcot2x was bs I'm convinced k was not an integer 😭

Geometric series one you're supposed to equal term4/term3 = term5/term4 to find theta=pi/6, then sub that into term4/term3 to get root6 as the ratio, then sub pi/6 into the third term and divide it by root6 twice to find term1/2, then add term1/2/3 together. Not a clue how you do part c) of the Algebraic integration one though, I got stuck in an infinite integration by parts loop

I got 2 for that one,

I flipped the "tan(a+b)" formula to get (1-tan^2x)/(2tanx)

then you expand the equation it gives you to get cotx - tanx which becomes (cos^2x - sin^2x)/(sinxcosx) -> (1-2sin^2x)/(sinxcosx)

you derive 1 + tan^2x = sec^2x, so you know that 1 - tan^2x = sec^2x - 2tan^2x

which becomes (1-2sin^2x)/(cos^2x)

therefore, cot2x is equal to (1-2sin^2x)/(cos^2x)(2tanx)

which is equal to (1-2sin^2x)(cosx)/(cos^2x)(sinx), so (1-2sin^2x)/(cosx)(2sinx)

which is exactly one half of the expansion above, so therefore k is 2
