Thanks, I watched the first video in this playlist then attempted to do the questions in this video without your help. I was completely new to vectors before I watched the first video and around 5 mins later I could manage to do all of the questions correctly on this video without any help. All I have to say is thanks for the explanations and your videos are so easy to follow and understand they have helped me so much!
+Ciamts - Hi ... it might be better if you have a teacher / tutor explain this as I can only really repeat what's on the video. The main issue is to prove that vector NM = vector MC (or is a multiple of). All best S :-)
I don't think you can do this because you need to show that both of the lines share point M, so by doing that you're not fully proving it's a straight line.

Thanks! I hadn't a clue how to go through with this.
Glad to help and all best S :-)
Thank you for posting. That is really clearly explained. :-)
you did it easily , tomorrow is my exam I hope this will help me , thank you!
ive been looking at this years vector question solutions and dont understand where he 7/2 comes from can you help
+Stephen Barker - Hi - happy to help but I'll need a drawing (not just a description). Can you post to dropbox or email to simon@3minutemaths.co.uk ?
Simon Deacon go on kesh maths the paper is on there
+Stephen Barker - It's the same as www.3minutemaths.co.uk/gcse-practice-papers/. Look for vectors in Grade A... which question?
Simon Deacon non the question is A O C is a triangle AB.BC is in the ratio 2.5 OA = 2a+b OB = 3a+2b express OC in simplest form in terms of a and b
+Stephen Barker - That's not on the paper but I'm sure I've seen it before. I'll look up - do a vid and let you know. Is that OK?
Is this grade 11 0r 0 level mathematics or
I'm really confused as to how you got b - 3/2b= -1/2b please could you reply and explain thanks
+Safwaan Patel - Hi - here's the rest of the playlist that might help? All best S :-) ruclips.net/p/PLPglScc3TJ-PD_fKk9j7lQ-maGxfLWLzk
+Simon Deacon I watched the entire playlist and I'm really confused as to how you got that answer also.

same
Dum guy
You can just do NM= and then NC=
yh thats exactly what i did
I don't think you can do this because you need to show that both of the lines share point M, so by doing that you're not fully proving it's a straight line.
May i know which variant from which year is this??
could you not just work out NC to form a straight line, it's much simpler or do the markers credit finding MC and NM
Hi - you need to show that NMC is a straight line. The easiest is to show NM = (a multiple of) MC ... around 5.54 on the video. Best S

+jordan lee - Glad to help and all best S :-)
Anyone here in 2023
Yep - I'm still here 😀
