Maths Ext 2 Predictions/Thoughts (2 Viewers)

[zakoht]

yeah thats what im thinking so i made a tof equation and suybbed in and everything cancelled nice

ah so u did the same as me, glad im not alone with my idea lol

 

[notme123]

the q16 a) proof though like bro didnt even know the triangle inequality was a 3d proof....

i got this whole q thankfully

YES, it just worked so perfectly and when it worked i was like surely this is correct and left it

 

[🍑 this is a peach]

said a=4 since v=8 when x=0 and n=2 for memory. but then again couldve stuffed it

i don't remember what i did but i definitely professionally fucked it up

Where’s @idkkdi I think we need to know what he thinks of the exam lol.

probs e z claps for him, he's celebrating rn

he got 101/100 obviously

He's probably doing Ext 3 now.

Probably spent the last 2 hours of the exam taking a nap.

Yea I got a=4, and what was the other part of the question again?

find what it alternates between

 

[Chungus]

farrrk are you kidding me. another 2 lost.

Bruh from what you’ve been saying you’ll get easy band 6, why you stressing

 

[Siwel]

also how did you do the triangle and hexagon numbers

i ended up with a value of theta 70.53<=θ<90

I got a = 5, since the centre of motion is x = 3. What I did was integrate the acceleration function and evaluated the constant using the condition x = 0, v = 8. I got:



I then set RHS = 0, and got after dividing through:
in which I said the particle oscillates within the range .

That aside though, god this exam was aids. Never have I hated taking a math exam more in my life. The 2020 kids were playing recruit mode. Truly fearful for Extension 1.

2k-1, 2k

but those werent initial conditions for memory

 

[notme123]

First part you sub n = (2k-1) and then you get (2k-1)(2k-1+1)/2 = k(2k-1 = 2k^2-k which is h_k

Second Part:

i dont think you had to do all that
