Did anyone get 10 as the answer for x for the triangle? And did anyone know what to do for the Pythagorean triplet part??

jack.nugent.12
I got 10, you had to fill in 10 for x and prove it worked

aimer
Ohhh I feel stupid!

aimer
I just subbed the 10 in I didn't prove it worked though, hopefully I'll get some marks though

Aaron125
10 didnt equal, 0 did though

CaolanH
I got 8.2..

aimer
10 did work though. I got 1 and 10 but if 1 was an answer you wouldve gotten a side with length 0

Aaron125
10 only worked if you squared the 4 with the x which you don't do when you have the variable (10) though

I'm not sure why everyone is so happy with the paper. It was much more difficult than the previous 2 or 3 years. Did everyone get 8 and 13 for the bees question?

Aaron125
yea you could check the answers with that long formula at the end

BebGoldof
the 200m sprint question was incredibly easy marks too but I despise rates of change

aimer
Did anyone else find that that new equation that have us didn't make any sense? I had No idea how to use it so I just counted😂

BebGoldof
I dunno but I realised I fucked up the simultaneous and Pythagorean triple Qs which is annoying but it could've been worse

dard
what did people get for the acute angle for the bastball net?

CaolanH
29 degrees

dard
did you just use the derivative to get the slope at the basketball net had use 1 for the horizontal slope then the tan formula?

shannon8
Think I got 34 degrees or there abouts

aimer
I got 32😊

aimer
I got 32 I think😁

aimer
Did anyone else find that the BEE equation they gave us didn't make any sense? I had No idea how to use it so I just counted😂

shannon8
Could've been 32 I got! How did you do it? I couldn't understand how to work out the bee formula so I extended the diagram thing to find G6 and G7, hopefully get a few marks for it anyway haha

dard
i just used the last formula they gave you it worked but i didnt show subbing into the first formula

aimer
I draw a triangle from C to the max point, then down to the horizontal i drew from C, left. i got the Y value (opposite) by taking the Y coordinates away (C and max point ) then the X coordinate(adjacent )
the same way , then worked out tan to get the angle. Not sure if that's what you were support to do though

aimer
*drew

aimer
Anyone else do it like that?

Aaron125
I did something similar but then I was told it was wrong because that gives you the angle if it were a straight line and not a curve :L

ronanomalley
i got 52 degrees by using the dy/dx of the parabola that you worked out in the previous part and using the x value of the point at the net. you get the slope of the tangent at that point then sub that into the acute angle between two lines formula using 0 as the second slope because its the slope of the x axis and you come out with an answer of 52 degrees or something along those lines

louisoc
the angle was 52, you got the slope using f'(x), then did the tan^1 of that, which gives you 52

shannon8
Ah I think i did that, so you let the angle equal the tan inverse of the y coordinate of the hoop over the x coordinate?

Lc8/6/16
Fairly tight on time as well. Nasty paper I thought

exam
I got 52 too ronanomalley and louisoc even though the whole world is saying 32

PCM123
Also got 52

PCM123
What about the trig differentiation question

CaolanH
Lol how the hell did I get 29

exam
I got .15 for the slope in the trig differentiation but I wasn't sure to use pie or pie in radian form

anonymous1234
BebGoldof. I got 8 and 13 as well and these are right because when you do a trial in the bottom in the formula this is what you get.

jozx7r
I got 52 as well but I think it's wrong? I done the horizontal from A, but the Q was the horizontal from when it went into the hoop .. maybe the two answers are the same though!

Fjfj
I got 52° as well by using first derivative as slope and subbing in value of x=4.5 and then used tan inverse to solve

AHHHITSAJELLYFISH.NO.ITS.CREAM.CHEESE
What did people get for the trig differenciation question?

aimer
I think mine started off with 1/xcos (1/x) something like that but I cant remember

Chloe murphy686
I'm just curious but I did my simequations twice and I still got the same decimal figures anyone else get decimals. All and all the paper was manageable way easier than the pre papers

Fjfj
I got sin(1/x)  (1/x)cos(1/x) i think

Alexw
ye i got that too using product rule
