what proof by vectors can they ask you for extension 1 (1 Viewer)

[v.tex]

Is there a specifric set of proofs they can only ask you, or is there a wide variety?

 

[C2H6O]

The range is quite wide you could be proving many things but all within 2d. Some of the things could be to do with right triangles, dot product proofs, circles etc. im away rn but ill try send a few example questions from my trials like tonight

 

[C2H6O]

difficulty 3.5/5

14 difficulty 2.5/5
16 difficulty 3/5

difficulty 2/5



difficulty 2.5/5

 

[C2H6O]

I'll try find a couple more difficult ones later off the hscs. unfortunately i seem to have thrown out a lot of trial papers made by my teachers

 

[C2H6O]

2023 14 c ii difficulty 4.5/5


2023 q13b difficulty 4/5 (you may or may not know how to do this one yet)


2022 difficulty 3.5/5


2022 q14 b difficulty 4/5


2022 q14c difficulty 4.5/5 (again you might not have learned this yet)


2021 q14c difficulty part i 1/5, difficulty part iii 2.5/5 (difficult to know where to start at first though)


2024 q12a difficulty 1.5/5


2024 q13c difficulty 3/5 (maybe it isn't supposed to be this hard but i remember fing this one up)


2024 q14d difficulty 4/5

ive skipped all multi choice and q11 vectors cause they should be really standard.

the main types of vector questions in q12-14 are:
algebraic type proofs (tips: interpret geometrically, look for expansions of dot products, use known facts)
geometric proofs (quite standard)(tips: define 2 vectors which cannot define each other (not parallel, for example) and start from there)
projectile motion (usually very methodical, but can get complex very quickly)
q14 proving crazy scenarios (tips: use past parts and try break these results down geometrically or expand to help you)

Thanks so much

Can you please tell me where these questions came from.

Can you please tell me where these questions came from.

these are from my own remaining past papers from last year
