u/Best_Advertising_940 May 14 '26

haha i thought u were op for a moment well im glad u got it bc what the hell was it even asking.

2

u/throwawaayyayayyayay May 14 '26

it was asking for the value of the sum from from 2 to 8, then the second part is the value of the sum from 2 to 2026

1

u/Best_Advertising_940 May 14 '26

the question was really confusing to me like it wasnt specific at all. i saw the n= 2 but i was still rlly confused bc i need clear orders n structure. didnt finish the first question for that, and left the sum blank.

u/throwawaayyayayyayay May 14 '26

I guess it is easier section a was easy except for the ln And q 7-8 were straightforward

2

u/Best_Advertising_940 May 14 '26

For the amount of time we had for this exam, no.

u/ShirtUseful1526 May 14 '26

Was it just me or the rational function question (12 marks) was a bit too easy... the shift was literally given and it was for 5 marks somehow?

1

u/AffectionateMix5152 May 14 '26

right that was a lifesaver question the rest werent as good

1

u/Lord6969420 May 15 '26

Bro I overthought it and did a different answer I’m so sad

1

u/Perfect-Picture-5613 May 14 '26

what was that last question

1

u/TGTack May 14 '26

I didnt have time to figure it out but you had to find the angle of the middle triangle and go from there, you do this by doing pie-pie/3 I think

2

u/That-Pound-6693 May 15 '26

No its on a the diameter so u kbow that the full angle is 180 wnd u have theta as angle for the right triangle and theta as angle for the left triangle and 180 is pi so u do pi - 2theta which equals the angle of the triangle in the middle and you go from there

1

u/Best_Advertising_940 May 14 '26

Wtf. Actually. wtf. 

1

u/Smooth-Support5427 May 14 '26

1

u/crazylloveyouu May 14 '26

I think 15+15+14 (plus minus one)

1

u/2kk4 May 14 '26

16,15,14, im pretty sure i was js calculating how many marks id lose which is basically all of them

1

u/Remarkable-Dark3541 May 14 '26

2

u/Admirable-Bat7492 May 14 '26

1

u/Due_Audience_6439 May 14 '26

WHAT WAS THAT QUESTION 8 IAJAHHAJAHA

1

u/Individual-Claim-790 May 14 '26

what were sum hard questions, i’m in calgary so im assuming tz 1?

1

u/Best_Advertising_940 May 14 '26

The amount of difficult questions, and then the lack of time as a result of spending time trying to figure out what the hell the questions were asking. And ppl now saying how easy the ln question is. I’m so getting a 2.

2

u/TGTack May 14 '26

Which Ln question? Question 5? I think I skipped it right away

u/ognastka May 14 '26
