A-Level Further Maths C3-24 3D Matrices: Deriving the General Rotation Matrices

[simonbalfe]

you are literally the most helpful person on the Internet for maths tutorials, no one can explain as well as you do :)

[Kevin_Guo]

Awesome explanation. I have spent hours trying to understand 3D matrix transformation and this is so clear! Thank you Jack.

[ruhan]

Thanks for the explanation, it was really helpful

[heidarsafari]

Thanks a million for your perfect teaching, sir.
In my my opinion, you are a super perfect mathematician because you were the only one who demonstrated the proof of rotation matrices.

[temesegenabuhay]

thanks alot sir before i see this video i am so confused how it was derived now the problem is solved

[samran]

do u have to memorise these for ocr mei? Thank a lot sir.

[joshplayz]

Could you make it even more general by instead of having coordinates (1, 1, 1) do it on (a, b, c)?

[jonathandwyer]

Thank professor. When a question is asking for a degree do you just apply that degree to whatever axis rotating?

[musaabaz]

Thank you very much for the explanation. I do have a question:
How do i know if it rotate with clock wise or counter the clock wise.

[JJFHNREHJEDK]

If you are doing edexcel where you aren't given these in the formula book, would you memorise or derive?

[hahabearseathoney]

i hate how the y axis rotation goes cos sin -sin cos instead of cos -sin sin cos, i always get it mixed up

[nosir]

Are we required to memorise each of the reflection and rotation matrices for both 2D and 3D? Or will it be given to us in an exam?

finally know why it is different for the y one...
