worst exam of my whole life hated that probability question as well ugh

what book do you have?

i dont i know iv got close to no hope on question 6/7, so i just work thru at my own pace, trying not to make any mistakes in the first parts then do what i can in the last questions, trying to scab a few marks in the trials, i had enough time to attempt everything and go back over it id say...

you mean 3a? the volume question? i have pi/3 x pi/4 = pi^2 /12, which is whats in the back i think ur answers are wrong

good luck everyone hopefully its as good as the 2U paper if not.... whatever its just one unit ext maths has been worth it just for our cake day so im happy either way

i only got 3pi/4, the rest werent in the domain and -3pi/4 is neg for sin anyway

zero study for ext as of now hopefully get some in today but if not, dont care too much if i pass, im happy

3u. wooo circle geometry and induction here i come

i did the same thing doubt we'll lose marks, it was only a 2 mark question or whatever eh whatever

i didnt find 10 that bad the beam one i just kept going without a clue where it was leading hopefully got something along the right lines then again, i did sorta plan what to do with 10 cept accidently got x/s instead of s/x for a bit. even though i had already worked it out right

awesome i got l/rt2 as well to find mp, i proved the triangles were similar, so mp/l-x=s/x or something like that

Re: General thoughts heaps better than i thought it would be so demotivated though, my lack of studying has been rewarded with easy exams (bio as well)

was pretty good esp compared to the other years what did u guys get for the last bit?

well i think the prac for that is the bromine water one alkenes react readily, discolouring the bromine water as they have the reactive double bond alkanes only react in the presence of UV light dont know about implication or application though

yeah its only 0 to 2 for y as root(4-x) become root 4, and its only pos only between -2 and 2 when its y^2, not when the root is there

ouch i cant even get to the product rule bit

(1^2+1)1!=2 1(1+1)!=2 true for n=1 assume true for n=k 2.1!+5.2!+........+(k^2+1)k!=k(k+1)! let n=k+1 2.1!+5.2!+......+(k^2+1)k!+((k+1)^2+1)(k+1)!=(k+1)(k+2)! k(k+1)!+((k+1)^2+1)(k+1)!=(k+1)![k+(k+1)^2+1] =(k+1)![k^2+3k+2] =(k+1)!(k+2)(k+1) =(k+1)(k+2)! therefore, true for n=k+1...

yeah, same. Whilst waiting for the impending doom that is extension maths We have a plan though. Cry through the whole thing...

i wasnt sure when i did it either but worked it out to be november bit iffy though

ok cool. thanks for explaining it i seriously learnt nothing in bio. except why the sky is blue thank god for bos
