It's my pleasure :smile:

To be honest I've been mainly relaxing after 2 tiring years of A Levels haha :biggrin: I'm also going to spend a lot of time with friends and family. As the holiday progresses I plan on going through maths/physics problems and dipping into first year stuff so i don't go totally brain dead haha.

What are you doing during the holidays? Has your term finished yet? :smile:


Yup im off school for a couple of weeks now i relax and what not still but ive started preparing all the topics i dont know and trying to figure out stuff i need to know for uni applications since its not easy for us internationals, not easy on the money too haha
Someone told me that a lot of simantaneous equations are used in some answers
Is it true A lot of those appear

Follow up on my previous reply on the thread I wanted to ask you HWO imp you think edexcel m2 is Ik parts of m3 are imp but what happen m2, they don't really ask centre of mass question and all that
Could you have a look maybe?

Sorry to bother you again but right now I have 3 alevels and I don't take further maths I tried asking my teacher for a predicted for AS further maths at least even tho she didn't teach me any module it's not offered in our school and she said she's willing to give me an A for As further maths, so I could submit this to Oxford but I was wondering if there was a point of As further maths or if I'm not taking it to alevel there's no point because I think they've Said as further is enough? I'd have to study the 3 extra modules next year and self teach them ( you think this is viable without hurting the subjects I might get an offer in)

I have seen them come up before, bu I can't remember how often. Even if they do come up they're incredibly easy anyway!

With Edexcel M2, the topics which are important to learn are projectile motion at an angle, motion with variable acceleration and energy problems (KE changing to GPE etc.) Finding the centre of mass is not on the spec but isn't that hard to learn.

It's no bother at all! :smile:

I think self teaching the whole of A Level FM would be a tad difficult, but possible nonetheless. I think if you do up to AS FM you should be fine (depending on the modules)

Also Oxford understand that not every school does FM, so if you just did AS and mention in your personal statement 'I am teaching myself AS Further Maths as it isn't taught in my school' they could see it as independent learning and it would work in your favour.

No AS FM wouldn't have a big impact at all on your other subjects if you manage your time properly. Because you're doing Maths you'll be revising that somewhat while doing AS FM. :smile:

Thank you!
Can you tell me why resistor 5 is being ignored from the last part of the calculation?

The picture isnt clear so question 25 on here

When two resistors are placed in parallel, the voltage across both the resistors is same and equal to the total voltage. So the voltage across 5th resistor is equal to the voltage across remaining 4 resistors and need not be taken into account.

You could, if you wish solve the problem using current divider (Voltage divider is used in the solution).
Following sheet provides explanation with some examples on current and voltage divider:

Thanks i totally forgot about the current equation you have some useful sheets!
Do let me know any more nice pdfs you have ill gladly look at them thank you again!

:yes: You are very welcome. What are the topics you mostly find difficult?

I haven't had a chance to go through them all yet so I'll ask as I go but if you've got anything you found really useful so far do send it ahead

Did you have a look at this one: http://faculty.uml.edu/rbrent/131/LF/Lect26.pdf

Yeah you told a bit earlier that certain pages to learn complelty and some partially

Also have you seen any torque questions on the PAT?
Original post by tangotangopapa2
No, you don't have to learn all of those.

Following is the link on what you should learn. Make sure to ignore (if you wish) the sections you don't need.
Page 1 : Learn all of it.
Page 2 : Ignore half angle, sum and difference, product to sum, sum to product formulas.
Page 3 : Learn the circle.
Page 4 : Ignore Mollweide's formula and Law of tangents.

http://tutorial.math.lamar.edu/pdf/Trig_Cheat_Sheet.pdf

Find the topics mentioned here and study only those first.

Yeah here is what you said, did you figure out what to eliminate by looking at the past papers and syllabus?

I told to learn certain page completely and certain partially for the sheet on trigonometry. This " http://faculty.uml.edu/rbrent/131/LF/Lect26.pdf " is on curve sketching which I would recommend to learn completely.

Regarding torques, it is not explicitly stated in the content. But it is good idea to learn basic about moments (though it is physically same thing as torque, it looks simple if you treat it as clockwise turning effect and counter clockwise turning effect rather than treating it as vector product). Either way these two short videos should cover all the basics:

and

Could someone tell me why the right answer is A and not B to question 17?

Look at the answer and all the comments to the answer. I think this will convince you why answer is A.

So basically as it's velocity is decreasing more and more eventually it will not have enough velocity to stay on track? (So at some point gravitational acceleration is going to be decisive against centripetal acceleration?)
