Vectors question

[glossy folio]

I do not understand this question

[eternal idol]

U basically finding outside ways to get BC

Lmk if u don’t understand

[glossy folio]

Thank you

[eternal idol]

I think I swapped the I and j around in the middle

But they both same answer so it’s fine

[glossy folio]

I understand the sin(45) and cos(45) but why are you able to just chuck that in front of the i and j?

[eternal idol]

Bc they both got the same factor

So u can factorise them out

I’m pretty sure u can leave it out

[glossy folio]

ah okay

and with the green and yellow lines how would you find the legnth of it

of them

For some reason I just can't my head round this qestion

[eternal idol]

Emm bc the green and yellow line are vectors the length (which is the resultant length) would be 1

[eternal idol]
