You made it look so easy. I was rote learning it. Now I may just do this whenever I feel confused about it all.
Wow, this is EXACTLY what I needed!. There is a proof of the Law of Cosines by way of vectors in a Classical Mechanics textbook of all things and it uses this exact property; very beautiful.
thank you bro!
can you make examples math & flutter to interactive more deeply ?

That sounds like a great idea! Anything in particular you'd like to see? I'm thinking a good place to start is using math to draw shapes in a custom painter
wtf this the only helpful video on this topic
