A-Level Maths: J1-01 [Vectors: What is a Vector?]

[karotic]

just navigating through your google website and I have noticed that you haven’t included the sub topic in vectors in relation to north east i=j or moving south east i= -j etc

Is this because you consider it to be out of the AQA spec? I was taught it in college.

Hi Mr Jack. I had a question regarding the as math that you are teaching. I am an IGCSE student I am studying as math (edexecl ). In the past papers they are asking to give our answer as a bearing. Unfortunately I didn't find any thing about that in your videos. Is that because you are teaching cambridge as math? Thank you for your time and your videos they helped me much. I am so thankful.

What’s the difference between a position vector and a unit vector?

Hi, just a question, how do you prove that two vectors bisect each other?

Hi, I was wondering if you can explain how I would find ratio lengths of a vector?

Example question:
AB=5a-3b
AC=7.5a-4.5b
Write down the ratio of the lengths AB:BC.

Thanks in advance
