****Leaving Certificate: Higher Level Maths Discussion****

Peregrine

In one of the very last parts, it said something like show that it increases with time and mine was decreasing

I think I now know why though..

Im gonna have 2 get like an A in paper 2 to make up for this crappy exam... anyone else in the same boat?

3/2 or something like that ... Can't remember exactly what I got . Could be plus or minus

Yeah I got that, think it was + but not sure :pac:

The marking scheme for last year's paper deducted one mark for people saying 8915 years when the required two significant figures (8900) so I imagine it would be the same this time.

53 degrees for angle using cosine rule ?

Huell

Ehh ok paper, sequences and series was tough i thought. Our examiner started 4 mins late and finished at 4:30 its bull**** tbh i know its only 4 mins but so much can be done then

Yes me too. I'm gutted.

I used the tan theta with slopes formula but yeah 53°

Yep that's what I got!

And I got 53 for the angle between the lines?

I got 53 degrees by finding the slopes of the lines and using a formula in the log tables.

Did anybody get the question with the rectangle? It something was like PB^2+PA^2+PC^2 = 3x^2....., I got two of the sides but there was one I couldn't figure out one because it wasn't a in a right angle?

eefah

So in light of this paper, what do we need to know for paper 2? Anything that comes up on both papers that wasnt tested here ...?

Daniel2590

I nearly missed the last question on the first page asking to draw the graph of the line :pac: saw it with like 30 seconds left

Mr Pseudonym

Geog paper just gone up.

I did that as well, got the same answer

Some answers I got:
53 degrees on Q2
1 for average value
2 for a on Q6
4 for k on Q7
240 for the area on Q8
77 for a on Q9, -.0339 for k I think!

guys, the geography paper has just been uploaded, hopefully that means maths is next.

You had to make 3 right angle triangles, one had sides 2 and x, 2 and 7-x and then 2 and 5-x I think off the top of my head.

its up!

So I finally decided to make this account cause fXxxxx that maths paper didn't even cover the dynamics of paper 1 fully. I thought questions 1/2/3 were pretty easy however it went downhill after that for me. I knew series and sequences well but only quadratic, cubic and geometric. And weren't part 1 and part 2 of the series and sequences question pretty much the same? I also was severely caught on question 8, the one with that weird parabola or whatever it was. How did ye get D and E? I think I got the answer but I am not sure. I thought the last question was though.

Overall, I feel sceptic about this paper. I am a B1-A2 student and I think I barely passed this paper. :"( I am not upset but genuinely angry with the chief examiner or whoever he is. LOL.

Can we start talking about paper 2 and what we need to revise? I am too caught up with not seeing Area and Volume and Financial Maths in todays paper.

Yeah I didn't know how to get that last side

I remember those, i got the same But I can't remember other questions you wrote

I did everything except Q2 a) and Q8 last two parts, I think it was completing the square but I couldn't do it the last few minutes anyone got those?

Mine was too; any idea where you made the mistake as I seem to have done the same thing and I'm not sure why (I specified why I thought it was decreasing on the paper, but I'm unsure)

Yes I need an A in paper 2 now to not fail my leaving cert.

And I wasn't even worried about maths at all haha

Good thing it was only a line

TooMuchStudy

Did people get D as (10,5) and E as (38,5)

BlueWolf16

How.. what is that thing that is under q6? I swear I've never seen that kind of question ever before in my life.

is the answer, you just substitute n into 1,2,3 and that's it? That's what I did atleast.

I put the equation equal to 5 and solved for x to get D and E.
As long as you wrote down everything you could you'll be fine. You probably did far better than you think.

I'm presuming you missed the PB^2.

That was tricky, you had to draw a vertical line from B (I think it was B and that created the third right angled triangle which allowed you to work out the length of the side.
