Rotation Matrix for 2D Vectors

Physics Ninja looks at the derivation for the 2D rotation matrix. The matrix allows us to calculate the new components of a vector that has been rotated by some angle. Both counter-clockwise and clockwise directions are considered.

Man i have been struggling with this notion as IT engineer and after many times searching for the full explanation I have finally found it !! Cheers ❤️

[@asgoodasbread5559]

You're a legend. Great explanation , I'd already used your vidoes in the past for Electrodynamics and nothing has changed. Clear, concise and well-explained material. Thank you so much

[@PhysicsNinja]

Wow, thanks!

[@archerdev]

Science bless you sir for all of those great videos.

This is the only explanation that clicked with me

[@sufianalrawajfi]

Thank you a lot. This great video is clear now for all🥰

[@tomhaswell6283]

Thank you for this easy to understand explanantion!

[@athuldas44]

how can i calculate theta if i know a and b points

[@thegloriousquran1208]

How about when rotating around a non origin point?

[@PhysicsNinja]

Future video. First translate point to origin, perform rotation, translate point back to position. Everything can be written in matrix form.

@@PhysicsNinja thanks for the knowledge, i just made a targeting camera with it heh
