Thanks a lot ! That was really helpful !

Thank you, I wanted to use index notation because it proved really usefull for developping vector identities. But if this identity's proof does not lend itself to this notation, I don't see the necessity to use it. In one of your links, you posted this: \nabla (\vec{A} \cdot \vec{B}) =...

Hi, I am a engineering student and I am currently upgrading my maths level on my own to follow physics courses. While reading a book, I came across a vector differential identity that I don't manage to prove using index notation. The identity is the following: \nabla(\vec{A}\cdot\vec{B}) =...
