vectors

What Cambridge Lessons is this dot point referring to: ME-V1.2 Operations with Vectors - solve problems involving displacement, force and velocity involving vector concepts in two dimensions. If anyone has a question bank for the dot point, please send it through lol.

Im talking about this formula: I was doing a hunters hill high extension 2 trial and they asked to find the min value of |z|. Would I need to derive this formula or can i just use it in an exam?

Hi all, I don't really have a specific example question from a paper (will look for one), but this is the type of thing that I really can't seem to do - is anyone able to explain this? I.e., how to use projections properly to find the shortest perpendicular distance between two vectors? Thanks!

The question basically is: Find the shortest distance between lines r = i+2j+3k + lambda (2i+j+4k) and r = 2i+4j+5k + mu (3i+4j+5k). I don't get these sort of questions and I really need help. Can someone give me a solution that doesn't involve the use of matrices please.

hey!!! I was wondering if anyone knew how to solve part B for this question. I can't seem to wrap my head around it. The answer is x= -3. Thank you!!

I need help with part a.

Hello everyone! Can anybody help me to solve these question? (sorry I'm very bad at Maths, took me forever but I still couldn't figure out o_O) 1. (HSC 1982): A biased coin is found to have probability 0.7 of showing a head when tossed. b) What is the most likely combination of heads and tails...
