I cannot stand long conic sections questions, I'm actually terrified of them

Yeah, the proofs and loci can be pretty annoying imo.

Have you seen the YouTube channel Tayyub Majeed? He has model solutions to a bunch of FP1 past papers including 2019, which had one such question on it worth 11 marks

I used to feel exactly the same way a week or two ago. But since I’ve ‘drilled’ about 40 or 50 of them I actually feel really confident. I’m sure if you just pick up the text book and specifically revise conic sections over a number of days you’ll too be fine.

Yeah I have :smile:

They're good, but to me the issue isn't understanding the solution, it's being able to actually come up with it under time pressure.

Am I the only one ******** myself about the conic question we'll get? After an abysmal core pure 1 and ~90% on core 2 I really want an A* so conics better not **** me over

That is reasonable.

I would say the only way to actually learn to come up with the solutions under time pressure is to know how someone else approached a similar problem by means of watching them write down and explain a model solution.

No you definitely aren't the only one! Also we typically get two conic sections questions per paper, not one :frown:

I am hoping that we don’t have an 11-mark proof like on the 2019 paper.

I also hope the first conics question is early on in the paper and similar to the first question on the 2021 paper.

Yeah but usually the first one is easy and early in the paper

Yeah I hope we don't either. The 2022 paper had nice, split up questions imo so hopefully it's like that this year! Then again, the 2022 core pure papers were really nice and this year they were pretty hard.

Dude based on what you estimated on the other thread, you're currently on trajectory for an A* likely irrespective of boundaries. I wouldn't worry.

I know but core 1 really screwed me. I am confident on fp1 just need to be calm in the exam lol.

Did you guys know that if a 4D hypercone is sliced by a 3D solid (like a cuboid), you get 3D conic sections? You'll get stuff like spheres, paraboloids, ellipsoids and rectangular hyperboloids. I bet they'll make an application question on this lol

That would be really interesting, but I really doubt it will come up.

They definitely won't ask about that in the exam. Maybe if they had FP1&2 in conjunction they could ask about surface areas of revolution to do with 3D conic sections.

Who here has done the FP1 papers from mock sets 1 and 2?

Is it just me or was the mock set 2 paper about a hundred times easier than the mock set 1 paper?

can you please send them to me (or give me the link) cos I cannot for the life of me find them

Does anyone know where the x = 0, y = -6sin(theta) comes from Q10 (page 75)?
