Maths Methods (Exam 1): Discussion, Questions & Potential Solutions

[not.yet.a.nerd]

missed the last page, spent to long before I realised I had the symmetry on the (N+1)pi question the wrong way round ....

Don't worry too much, the last page only had 2 marks

[Nason]

I'm so surprised that the very last question was only 2 marks with how much working out was required.

Pretty decent exam.
No controversial differentiating at end point this year!!

[addictwithatextbook]

wow literally thought I was the only one. It was going great the whole way through and then bam last two questions slaughtered me

it was the last THREE questions that slaughtered me! oh goody...

and what was the equation for l1 in the last question?

Yeah, exactly, which makes me think that there must have been a more simple way of solving it. A friend was saying that you could use values found in parts a-d or something but honestly I have no idea. Guess we'll be waiting for the exam to be published :/

[Acynatic]

That was a complete wreck, got all the hard questions right but lost 4 marks to easy questions cause i had no time to check them...

[Atarasdf]

that was the easiest test in a long time 40/40. phew

LOL, liar


What did everyone get for K?

Hi everyone. Hope you all did well in your exam 1.
One of the questions gave us a derivative and told us to find the original function.
I Wrote:

But I now realise that a simpler form is:

Will I still get full marks even though I wrote the first one?

Yeah you could substitute that in when integrating xsin(x) however it still is a lot of working out

Also, do I have to justify the fact that I have no absolutes? The domain x>1 and I thought that absolute values when integrating weren't needed since it's out of the methods study design.

Don't ever disrespect the king

[addictwithatextbook]

Don't ever disrespect the king

lmao reminds me of someone in my class  definitely joking/sarcasm

LOL, liar


What did everyone get for K?

i guessed both k values because i had no idea how to use the definite integral

[DinWell]

LOL, liar


What did everyone get for K?

Pretty sure first k = 1 and second k = ln(2)

Can someone tell me how many marks question 6 was?
