in the last step, why did you multiply and divide with square root 2 ?
Just to simplify it more ..it's not a necessity .in the last step, why did you multiply and divide with square root 2 ?
thank u so muchhhhJust to simplify it more ..it's not a necessity .
And I just read the question it says no need to simplify the answer thus you can give the answer without multiplying and dividing by square root 2.
You are welcomethank u so muchhhh
I solved it rougly I hope it is understandableCan someone possibly show me the working of question 5, feb march paper 32 2019?
Yeah how was it? Fine paper but not enough time. Still did well enough to get an A* - best case scenario would be 71, worst case scenario would be 68 so I'll lose 5-6 marks I'm guessing.Welp, finally done with my exams.
Anyone else did 32 today?
Yeah time was tight for me tooYeah how was it? Fine paper but not enough time. Still did well enough to get an A* - best case scenario would be 71, worst case scenario would be 68 so I'll lose 5-6 marks I'm guessing.
Forgot about the constant in differential equation so one mark lost there, didn't attempt the expand sin(3x+x) and sin(3x-x) part at all as I ran out of time. So losing 4 marks and I could lose 3 more potentially for method marks in AB=2rcosx proof and differential equation part(ii) which was one mark(differential equation question was a repeat from march 2016 question 7 and the mark scheme only says 'justify statement' for part ii which is very vague).
Overall, everyone had problem with timing so threshold would be about 57-59 for an A in p3 and A* in maths will be about 228-230.
I am so exhausted that I remember very few answers. Usually I'll remember all the answers but this exam has drained the life out of me.Spaced out mid exam.
Couldn't finish in time.
Would've landed an A if I had better concentration.
Can anyone type in the answers if you remember them?
X coordinate in the last part wasn't this, it was greater then 1...the diagram clearly showed that it had to be between π/3 (the upper boumdary calculated for area in the previous part ) and π/2I am so exhausted that I remember very few answers.

1. Coefficient was 6 maybe(don't remember properly)
2. Log question: x=0.126 - don't remember properly
5. Complex number roots question: k=2
7. Refer for m16 paper for answer, answer is complicated and c=0 - differential equation
Plane question: Equation of plane M was 4x-2y-4z=5(signs maybe off as i don't recall this one properly)
Shaded region= 9/16, value of stationary point's x-coordinate=0.13
Iteration was the easiest of the last few questions so don't remember it at all.
Thank you for refreshing my memory. Yes it was 1.3(i mean that's what I got).X coordinate in the last part wasn't this, it was greater then 1...the diagram clearly showed that it had to be between π/3 (the upper boumdary calculated for area in the previous part ) and π/2
Yeah yeah I remember, I wrote 1.30.I got 1.2 something, it said write down your answer to 2 decimal places
Grade boundaries for A* might be lower like 225-227 because of Paper 12 as well. What do you think?Yeah how was it? Fine paper but not enough time. Still did well enough to get an A* - best case scenario would be 71, worst case scenario would be 68 so I'll lose 5-6 marks I'm guessing.

Unlikely that they will go below 227 for those that gave AS and A2 separately and not below 229 for those that gave AS and A2 together.Grade boundaries for A* might be lower like 225-227 because of Paper 12 as well. What do you think?
In that case let’s hope for a 227 Grade boundary for those that did AS and A2 separately. Fingers crossed...Unlikely that they will go below 227 for those that gave AS and A2 separately and not below 229 for those that gave AS and A2 together.
