Methods Exam 2 - How was it?

[Shenz0r]

9.5 is correct. Disappointed i just assumed to add 12.2 and 8pi/15
Just pigeonholed question as easy in reading time fml

Did the same, fuck

Finished it with 10 minutes spare - Just enough to check MC again
Was quite long I guess the cut-off for a B will be like rediculously low like 30/80.

Hope I didn't do many careless mistakes.

It was 20-12.2 + 8pi/15, right?

Yes

I had no idea how to do it and I'm pretty sure I got 0 marks for that question.

anyone remember how many marks the transformation question was worth in the ER? the one involving g(x)=1/x

I worked out the correct reasoning on the train lol, its because at time 20 there is 0 water, at time 12.2 there is 2 metre of water, therefore the time when it less than 2 is 20-12.2

But also when it rerises it takes 8pi/15
So add them together

I did all of the working out correctly for the question where we needed to find a and b but managed to get the answers wrong because I transcribed a value incorrectly from my CAS in one of the steps ): Would that be two marks lost, out of 4?

Damn, I was thinking that in the exam but I was like "when the hell is there 0 water"

Can't believe I forgot the information from the previous questions.

2 marks i think it was

[dfgjgddjidfg]

yep it was 2marks

yeah that was ridiculous lol, should have been a 4 mark question

[rocket]

would full marks be awarded if 8pi/15 was written as a decimal ?? to two decimal places ??

I was going to do that but the question didn't tell you to write in decimals. I think I left it in exact form.

I wrote both

when are you guys going to upload the exam?

yeah that was ridiculous lol, should have been a 4 mark question

Would it have been okay to have figured out the answers by reversing the transformations done on the original graph?
Didn't have much working out but I wrote out the matrix for the transformations required and then stated what a, c, and d was...

sorry to say this but you will lose a mark

This is what I did, considering that it's two marks I think it's acceptable.
