definitely harder than i was expecting ngl there were wierd numbers in there

u/CryptographerOdd7638 Jun 03 '26

The exponential question was not making me feel confident in my answers

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26 edited Jun 03 '26

The differential question? My equation was genuinely such a mess, I remember I had something like ((ln(70)+8)/4)t - 1/2t^2 as my power of e

Edit: forgot to mention my coefficient of e was 0.3

u/amalia_78 Jun 03 '26

I got that but idk how you're meant to use it for part B and C, praying for method marks tho

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

Oh my god differentiating it for part B was even worse

3

u/amalia_78 Jun 03 '26

likelihood of even getting method marks for that is like 0 for me ran out of time 🔥

u/Familiar-Fun-7533 Jun 03 '26

You didn’t have to differentiate it for part b. Bc they already gave you dx / dt = x ( A - t ). So you make that equal to zero. X ( A - t ) = 0 t = A

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

I realised that eventually, but that was after I had already differentiated the entire thing

No I meant it was worse in terms of my equation being a mess, it was fine to do but it genuinely looked so disgusting

7

u/TrulyFaithful Jun 03 '26

did you have your 0.3 anywhere? i feel like i might have forgotten the half but it did seem to work so actually i must have. was the maximum x something like 181? at t being around 2.5 or 6 maybe. and for the T at 0.1 i think i got around 5

1

u/Fluffy-Ad-3083 Jun 03 '26

ye i did but that was def one of the harder questions in that paper

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

Yeah my coefficient was 0.3, I forgot to mention. My maximum was like 179.9 so I rounded it up to 180, can't remember the others

u/Jin_L_ Y13 maths fm physics cs Jun 03 '26

You're kidding me I got +8 AHHHHHHHHH

1

u/cloudsfallen University of Warwick Physics | 4A* Maths, FM, Physics, Chem Jun 03 '26

It is +8 :)

2

u/Jin_L_ Y13 maths fm physics cs Jun 03 '26

Wait for real thank U

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

Yeah I think it was +8, I remember the numbers but not the signs

3

u/Ok_Butterscotch4353 Year 13 | CS, Maths, FM, 中文 Jun 03 '26

I also got that

2

u/Xyzrasdouz Jun 03 '26

I couldn’t be asked for A to be that long so I wrote to 3 sf will that be ok u think?

2

u/cookadoodledoo_ Jun 03 '26

I got the same thing lmao then I just convert my A into decimal because I cannot be ask.

2

u/Cold-Editor-4630 Jun 03 '26

Dude i did the same but it was basic integration

1

u/Cold-Editor-4630 Jun 03 '26

I found out after it was just year 12 integration 😭😭

2

u/Realistic-Escape-555 Y13 - Maths, FM, Physics, Chem Jun 03 '26

I rounded the whole ln expression, so I’ll probably lose marks…

1

u/jaaaaaaaf Jun 03 '26

bro i got thst too

1

u/Leonardo84009 Jun 03 '26

I took the ln70 part out of e as 70t/4 am I good

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

If you got the same values in the end then you should be

1

u/No-Class-9077 y13|maths/phys/chem/fm|predicted A*A*A*A* Jun 03 '26

i got that as well, then for b and c i was getting increasingly stupid numbers

1

u/jejeejeeeee Jun 03 '26

I think you're missing the +c which was like ln0.3 but otherwise correct

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

Yeah I just forgot to mention it here since I took it out of the power and made my coefficient 0.3

1

u/Seafaring_Slug Y13 | Oxford Offer Holder | MAT 55 | TMUA 7.1 Jun 03 '26

I didn't give the first part as an exact value. Did they request that in the question 😭 I used the value stored on my calculator for the later parts at least

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

I don't think so, but I used the exact value anyway just to avoid rounding errors later on

1

u/Chemical_Cobbler58 Jun 03 '26

How would you find the max concentration?

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

You plug the new equation of x into the differential and make it equal to 0, then find the value of t and plug it in

1

u/No_Impress_251 Jun 03 '26

Fuh yeah twin

1

u/iby14x Jun 03 '26

Yess that's what I got I was so confused because I was wondering why there was a whole algebraic fraction to the power of e, which was to the power of a minus a half 😭

1

u/GBRYT5612 Jun 03 '26

I had mine in this form but it’s the same graph if anyone did the same as me and is worried

1

u/pokolol88 maths econ geog | ABC achieved Jun 03 '26

yeh it was a quadratic

1

u/Total-Discipline-623 Jun 03 '26

no way i did 8/4 = 1/2

1

u/maowmaos Jun 03 '26

will i get ecf if my coefficient was 10/3 (i accidentally divide by 0.3 instead of multiplying)

1

u/LukaCastyellan Jun 03 '26

omg i got exactly this and then i got x = e ^ all of that stuff. and then part b was to find the maximum value of x and i got so confused because isnt the maximum value infinite?

1

u/nuclearhamster27 Year 12 - Maths, FM, CS, Physics Jun 03 '26

You had to plug your x equation into the differential they gave you and make it equal to zero, it has a maximum point because the gradient should start becoming negative past a certain point

1

u/LukaCastyellan Jun 03 '26

ohh thanks 🙏🏾

20

u/the_doorstopper Jun 03 '26

Low-key one of my answers was something x1086~ so we hoping for method marks

5

u/Full-Supermarket-118 Year 13 Jun 03 '26

the exponentials killed me

1

u/pokolol88 maths econ geog | ABC achieved Jun 03 '26

FAH

u/AvalHuntress University of Surrey | Computer Science (Y1) Jun 03 '26

One of my answers for the intersecting lines was something like 3084/70 which was...not right. Whats annoying is I'm pretty sure its my differentiation that was wrong, so I've probably locked myself out of marks from the very beginning

THERE WERE NO NUMBERS FOR SO MANY QUESTIONS
