Mathematics: Post your doubts here!

Guys I forgot to put +C after integrating in the integration question in mechanics (M1) , will I get Follow through for the next part? How many marks are going to get deducted ?

Maths Thresholds were so high in March

No bro, those are standard maths GT. You may check the June 2016 and 2017 thresholds. They are very similar to these.

Is feb/march 2018 out?

Hey where are the question papers?

 

[Mistar-Kigi]

I am expecting grade thresholds to be at like 80% for AS level maths(variant 2). Around 40 for M1, around 60 for P1, though I could be wrong about P1 thresholds since there were a few new ways of asking questions, and some challenging questions for most candidates(many made mistakes in the binomial question by multiplying the expansion, many found the values of f(x)=k tough, the question about range after you draw the sin and cos graph, others made mistakes in h and k and most often, people forget about subtracting volume of the line). This was the general response from schools in Lahore. So maybe P1 thresholds could be 55 or lower since there were so many questions that candidates found difficult.

Thresholds for paper 12 maybe like 56 or 57 but I really don't think threshold for 42 will drop that low. Will be around 44-45 by my guess!

 

[Mistar-Kigi]

Another question!

By any chance do you guys happen to remember the value of K in the question related to functions in Paper 12? Please tell me it was -3.

It was the same question in which they asked to find the inverse for the function. This'll probably help if you can't quite remember the question I'm talking about.

Well don't quite know about the questions found difficult but many candidates here said they missed out the questions due to lack of time for p 12.

k>3 and k<11

 

[Mistar-Kigi]

k>3 and k<11

What was the single value of K we were supposdd to state then?

 

[hellodjfos;s'ff]

There was no single value, there were two values, 3 and 11

 

[Mistar-Kigi]

There was no single value, there were two values, 3 and 11

Maybe we're talking different questions then because I'm pretty sure the inverse part said "For this value of K find f^-1(x)" or something like this. And in the very previous part ( which was worth 1 mark btw ) he asked to state the value.

 

[hellodjfos;s'ff]

Yeah not sure which question you talking about. I have forgotten most of the question in p1 by now hehe

 

[amina1300]

Statistics notes anyone?!

Yes you two were discussing different questions. The value of K for the function inverse question was -3

Ha! Thanks for the clarification. Btw did anyone appear in 9702/12 here? Need to ask some questions :/

Yes I gave that paper. What do you need?

 

[Mistar-Kigi]

Could you tell me that total energy transformed and value of Resistance of wire you got? And also the time you calculated in the last part of waves question.
Thanks!
