I am resitting C3 in the summer and during my revision have come across a few questions if people would be able to help...they're very basic!

1. Is using the short version of the chain rule acceptable or is it preferred to use the long version? It just seems like a lot of unnecessary work!

2. Do we need to know the proofs for product/quoitent rule and addition formaulae ie cos(A+B)?

3. Is Sin/Cos3A needed for the exam?

4. What is needed to be learnt from chapter 7 - the proof chapter ie deduction, contradiction and counter example? It all seems a bit basic.....

Thank you

1. You don't have to write out all the 'u=...', 'du/dx=...' stuff (although you may find it helpful for complicated questions). You can just jump straight from e.g. (d/dx) sin(3x)=3cos(3x)

2. No

3. It's not one of the standard formulas to memorise, but they could ask you that, or another similar question to test that you can derive it using the formulas you already know.

4. I'm not really sure but the type of questions you see on past papers would be the sort of thing you should learn.

Yes, there's a set procedure for doing all this. Have a look at http://www.jcq.org.uk/attachments/pu...ept%202010.pdf for all the details.

That is all fairly complex but I think I understand! haha
Is it done automatically or does the school need to do something? If I just leave it will it work out ok?

1. I'm not sure what you mean by short/long versions- if what you produce is correct then you get the marks.
2. No you don't.
3. What do you mean by this? If you mean in terms of being able to expand sin3a as sin(2a+a)=sin2acosa+cos2asina then sure and not just up until "3", they can ask anything they want involving these compound angle formulae.

1. Well we were taught two versions: one involving substition with t and differentiating parts seperately...then a short cut where you basically do it by eye...
2. Thanks
3. Ahh ok.

1. Ahh great. Thats what I meant thanks It saves a lot of time!
2.
3. Ahh. They're simple enough I guess...just use the orginial A+B version then use identities to get the final answer
4. Right. I'll have a look

If your maths a-level has already been certificated and you have your final grade then it may already be fixed where it is. If not then then that process should happen automatically.

If you're not sure then it's worth checking with your exams officer although in most cases this process should happen automatically anyway if they're doing the paperwork correctly.

Just adding to ttoby above, I imagine you're probably entered for re-certification anyway for maths A-Level (seeing as you're resitting C3). So having your modules 'fixed' to single maths won't be an issue.

In reply to both of you:
I'm in year 13 so have my maths AS level.
I started Further maths AS this year so won't be getting a full a level just AS.
I am resitting C3 yes......
Will it all be ok then?

You'll probably be ok, but it doesn't hurt to check to make sure.

Ok great
I'll ask my maths teacher :P
Thank you

If anyone's got any questions about anything, I've just finished my first year studying Maths at Sheffield and would be happy to answer anything

Good luck with your exams everyone!

Ooh!
Is Maths harder at Uni compared to A level?

I feel really bad as I loved Sheffield uni but I had 3 that i loved and chose the other two

A lot harder. But it's also more interesting...

My maths teacher only graduated from a maths degree about 4 years ago and didnt fill me with much confidence!! haha
Do you find its fairly easy to pick up or are there some things that are just impossible (obviously they arent but most of A level maths can be picked up fairly quickly...)

My personal experience is that I found some courses really easy and some very very hard. However everyone is different and so you might find different things easy and hard. I find lots of things impossible in maths, so don't feel you're the only one if you're in that situation.

You will have to work for a degree - the pace is a lot faster than A-Level. But you already knew that Remember that it's also a huge huge amount of fun too!

It's only natural to think about uni right now, but resist that temptation right now. Get through your A-Levels, chill out for a couple of months and enjoy uni. Best of luck (and to everyone else too!)

Ahh thats fair enough i guess. And maths is such a wide subject theres plenty of courses/modules to suit everyone!
Haha that is very true!! A levels are said to be harder than uni....
Hmm i know!! I'm trying! But it keeps drawing you back - accomodation, student finance.....

As Shamika said, it is a lot harder, but I find it more rewarding. And there's more variety too. Most of it builds on what you learnt from A level so it doesn't feel too much of a jump, there's just a hell of a lot more to learn, most of which is more complicated! My one main piece of advice would be to keep up with the work as you go along, as it's a lot harder to cram at the end. 3 of my modules were year long modules, and there's so much stuff that by the time you finish going over everything, you've forgotten the stuff you went over first! Don't feel daunted by uni maths though, you get used to it very quickly

Oh goodness!! This makes it sound scary! haha But yes i'm sure it is much more rewarding. It is more pracitcal based too? The thing i'm looking forward to is the variety and the fact you can choose certain things to home in on...
Which uni are you at?

This I agree with so much! Uni maths is enjoyable, but stay on top of your work from day one! (I ended up cramming for some modules, it was horrible )

Haha, don't let it scare you! It's exciting and as I said, you get used to the workload very quickly. I must say I always felt very smug throughout the year when my friends had essays and coursework to do and I didn't as a maths student! I found the lecturers were very good at bridging the gap between A level and uni maths. I'm at Sheffield uni. Where have you chosen?

Yes it will be very exciting! I can't wait
Haha yes that is one thing i'm looking forward to - since i'm doing english at the moment and sometimes its a bit like: oh not another essay!!
Ooh cool Is it good?
I had a top 3 that I found vv hard to choose between: Lnacaster, Leeds and Sheffield. In the end Sheff was the one that missed out And I firmed Leeds, insured Lancaster....
