Hi, I have a small question , now, In Q2, when calculating the value of vector, you chose BA.BC and Not AB.BC ,why? and when I tried calculating AB.BC , I got 26 and a wrong value of the angle.
Cuz it has to be the angle between vectors BA and BC (an obtuse angle), not the angle between vectors AB and BC. Direction really matters. Anyway, you can use AB and BC and you'll get an acute angle. To find the angle ABC, subtract this acute angle from 180 and you'll get the correct answer too.
In question 2, you have just written 62.3 unit squared which is just the area of triangle ABC, but isn't supposed to be 2X? So 62.3 X2= 124.6 unit squared for the full parallelogram?
Hi any idea what do unseen content April 2021 mean? So are those papers like the 2021,2020 locked papers or they will sent papers during the month of April and assess us during our mocks based on that?
The answer in 2a should be 26/7^93, no minus sign
the video helped a lot. thanks!

Thankyou
Thanks!
Can you please provide me Edexcel IAL Jan 2021 FP3 Qp and Ms!! Please!!

I already multiplied by 2 in the first place. You can see it when I find the area. I didn't use 1/2. So, 62.3 is the area of two triangles.
Teacher can u plz update S3 2021 January plz
Hi. It might take a while because I have to complete P1-P4, S1and S2 first. Sorry for the inconvenience.

I have no idea either. It really depends on teachers in your school. Hope you revise everything and be ready for the upcoming internal assessment 😁
@@revisionmania7254 I hope everything turns out good I am preparing just a little scared since broads make tougher paper
@@Lily108y It will. You got this!
@@revisionmania7254 thankyou
