Did you guys find Oct/Nov 2014 session to be particularly difficult by any chance? I had a lot of trouble with a lot of the questions and I was wondering if others felt the same. Is the latest session a good indicator of what to expect tomorrow or is there no telling? I'm particularly bad at the following:

- Integration (Particularly when the question is about an area with a shape involved)
- Connected Rates of Change/Chain Rule
-Some Trig Identities
-Finding the Range of a function (any idea how to do this?)
-Sketching Trig Graphs
-Circular Measure is easy most of the time, however, sometimes it really takes some concentration.

 

[Zash Riyash]

It might vary from each person, like I found the paper very easy. But you could do integration using your calculator, trig identities are a real pain at times! For finding the range, they give a certain domain, so as per that you determine the max and min value possible.

Sketching trig graphs could be done from your calculator
Rates of change is not that difficult u just need to identify whether the rate given is increasing/decreasing in x or y and apply the formula
Circular measure is tricky but remember it just revolves around the area of circle/sector/triangle and pythagoras theorem

Assalamualaikum.
Can someone please solve oct/nov 2005 question 9)iii) with the perfect steps? I know how to get the answer but I'm worried about the presentation.
Jazak Allahu Khair

Nov 14 papers are not that difficult just something tricky
Also for integration if founding out the volume and you need to subtract area of rectangle or triangle then just transform it into a 3d shape so a rectangle becomes a cylinder, triangle becomes a pyramid

To be honest the Cambridge guys, aren't seriously bothered about presentation as such.

Yeah but I need to put sth on my paper, don't I? I can't just solve it in my head and go like hey this is the answer
Could you just solve it please? May Allah bless you

What are the formulas which we need to learn are not given in the Formula Booklet?
Thank you!

The area formula, discriminant, vectors, trigo, I think that's it.

Can you Plleeaasssee write down the formulas or attach all of these? Thanks!

Q.5 (i) how do we tell whether it has an inverse or not

Q.5 (i) how do we tell whether it has an inverse or not

f'(x) < 0 hence np turning points as denominator always >0 and numerator -ve overall f'(x) will be -ve, hence has an inverse.
