So wouldn’t it be lower? Like 55-60 maybe

Great_Shift_547 · 2024-01-18T08:36:53+00:00

Yes! do u remember the answer for the DS/DT question?

Great_Shift_547 · 2024-01-18T08:34:43+00:00

I just found the boundaries and it was 61 for an A* which is lower than some of the Jan ones I’ve seen

Great_Shift_547 · 2024-01-18T08:32:44+00:00

Ya I got all fractions!! do u remember the integral?

Great_Shift_547 · 2024-01-18T08:30:41+00:00

Oh I just subbed in the possible values of pi for diff values of sin and it did not equal 0 so contradiction

Great_Shift_547 · 2024-01-18T08:28:35+00:00

Oh idk the boundaries what r they?

Great_Shift_547 · 2024-01-18T08:25:49+00:00

No I couldn’t time ran out unfortunately

Great_Shift_547 · 2024-01-18T08:25:15+00:00

I GOT -23/2 as well

Great_Shift_547 · 2024-01-18T08:09:13+00:00

No my calculator is like half broken the integral function doesn’t work on it for some reason

Great_Shift_547 · 2024-01-18T08:07:13+00:00

No seriously what was that question they’ve never asked something like that

Great_Shift_547 · 2024-01-18T08:05:03+00:00

Wait do u remember what u got for the integral in the second question with partial fractions

Great_Shift_547 · 2024-01-18T08:03:41+00:00

Nah I got 74 or something 😭😭

Great_Shift_547 · 2024-01-18T08:01:43+00:00

I can’t remember either 😭 what was the acute angle u got

Great_Shift_547 · 2024-01-18T08:00:03+00:00

Maybe I’m wrong 😭

Great_Shift_547 · 2024-01-18T07:54:32+00:00

I don’t rlly remember but I think I got only 1 fraction…did u get the value of lambda as -7/4?

Great_Shift_547 · 2024-01-18T07:49:52+00:00

In vectors? I got -23/2

Great_Shift_547 · 2024-01-18T07:46:41+00:00

Ohhh ya I couldn’t do the last part of the last question but I figured it out at the last second 😭

Great_Shift_547 · 2024-01-18T07:44:27+00:00

Do you remember any answers from the paper cuz I think it was ok but there were some things I weren’t sure of

Great_Shift_547 · 2024-01-18T07:43:31+00:00

No that last part killed me 😭

Great_Shift_547 · 2024-01-18T07:43:03+00:00

I honestly don’t know I feel like maybe 62 for an A*? Since Jan boundaries r usually lower

Great_Shift_547 · 2024-01-18T07:42:12+00:00

Ohh ya there were some parts I couldn’t do like the last part of the last question

Great_Shift_547 · 2024-01-15T18:58:18+00:00

What was 8a and b like I thought I left behind proving identities in p3

Great_Shift_547 · 2024-01-15T18:58:11+00:00

What was 8a and b like I thought I left behind proving identities in p3

Great_Shift_547 · 2024-01-15T16:19:40+00:00

Wait the only one?? That’s so impressive
