Yeah, you usually just find the modulus of the vector but be careful to show all the steps in your working I think?
Thanks! I just wasn't sure how explicit to be in my workings - whether I should calculate it and factorise, or simply state "because sin^2x + cos^2x = 1..." and just calculate the magnitude using the coefficients squared
I'm just realising that although M2 is challenging (it's A level Matjhs after all), it's not too difficult once you read the question properly. It actually makes it much more enjoyable.

I get what you mean. The questions are all doable but it's hard to spot if at first!
Doing OCR A physics, unit 4. It's quite easy I should be able to do it, it's like M2 but simpler and with a couple mor physicsy topics thrown in. Managed to get 80%UMS in it last year and I ran out of time with 12 marks worth of answers left 😩
I'm thinking 57-60 for core 3 and about 64-67 for core 4. I'm hoping the c3 grade boundaries are like last years core 4 ones and then I might be able to get an A* 😂 not much chance after c3 though

We can all hope. I'll be back on the day before results day when boundaries are released on the thread to see people's opinions
Have you got any advice/tips? I'm rubbish with wordy questions!
I went through the book and tried to make a model answer for every wordy question that could come up pretty much. I'm usually awful at anything to do with writing but I really enjoyed the unit so I didn't mind learning it. And I'm not saying don't do past papers, but it think I did 2 for that exam and it was my best mark, I just read the book a lot and took a lot of notes.
Youll definitely have an A* if you managed that ridiculous score in core 3 haha. And I'm not sure what to think of the core 4 grade boundaries, I'm thinking maybe 63 or so for A*, I really doubt it'll be more than that! as it was a fairly straightforward paper but a lot of mistakes will have been made.

Yeah I've no complaints of the core 4 paper itself. It was me who made the stupid errors lol.
Just doing past papers and using the revision guide. I still have 5 exams to go so yet, quite a lot. By the end of this week I will only have three exams left so I can focus a lot more on M2 with C3 and C4 out the way. Do you have many exams?
