ur videos have helped me so much. as someone whos currently self-studying further math (cie as) its scary knowing that i do not have any guidance (not even a side tutor) but ur vids give me the sense that i have an actual (GOOD!!!) teacher guiding me along the process. its a reassuring feeling, thank you so much.
Is it potentially possible to do all of this using a reflection matrix? The transformation would be non-linear(which is beyond the spec), but I'm just very curious...
Hmmm we just need to reflect any point that is on the line in the plane, so we just pick any point, and then find its perpendicular line through that point to reflect it.
ali xone Hey - so we use the Pearson Edexcel textbooks, which is the questions that I sometimes refer to on my slides - for example here I suggest Ex 9F Q8, 12. I’d recommend getting this textbook, and then my lessons pretty much follow those exercises!
@@alixone4533 This is something I may be able to do in the future, but at the moment don't have enough time to do. I'm sorry! The textbook and exam papers are more than enough.
I mean revising to understand, revising to practise skills, and revising to memorise facts. They are 3 different stages - you must understand a concept before you can practise it, and the last thing you need to do is memorise the facts to help you be speedy!
Thank you for putting so much work into this channel, it is really helpful!

Thank you for the lovely comment! Good luck with your studies 🍀
how did you end up doing?
this confused me so much i can’t thank u enough !
I'm hoping you mean you were confused before, and now you're not! Don't want my videos confusing you hahaha
no i meant u saved me 😂
So many step but highly cognitively demanding. That's what I like.
It's a good idea to write a 'to do list' at the start so you remember what you need to do!

Yes I should think this probably is possible... but exactly what that matrix is eludes me without a lot of thinking... hmmm...
At 8:38 when you dot product the vector perpendicular to the plane, I thought it would equal 0? Why doesn't it in this case?
Thanks!!!
That's only when we're talking about 2 direction vectors, and here one of them is a position vector!
@@BicenMaths Awesome!! Thank you so much great content as always!! Goodluck for your exams too :)
How do you know when to use the method in this video or the method in the previous video in this playlist?
This one is reflecting a whole line, not just a point - whereas in the previous video we were just reflecting a point!
Thing the thing I dont get is that 2,4,-6 is a point on the line how do we know its the point that is perpendicular what if it was somewhere else
Hmmm we just need to reflect any point that is on the line in the plane, so we just pick any point, and then find its perpendicular line through that point to reflect it.
Is it possible if you can upload questions to do after each video ?

Bicen Maths yeah I see that. But you also sometimes put past exam questions or worksheets online too for ur students?

At 9:15 is Lambda = 0 at point (2, 4 , -6)?
Yes
you talked about 3 types of revision- what did you mean by this towards the end of the video
I mean revising to understand, revising to practise skills, and revising to memorise facts. They are 3 different stages - you must understand a concept before you can practise it, and the last thing you need to do is memorise the facts to help you be speedy!
@@BicenMaths brilliant makes sense. And for this vectors topic because there’s so much what do you recommend doing to get good at this topic
