Vectors & Gradients: Confused? Get Answers Now!

[Hayden Herzberger]

I was watching a video explaining Einsteins field equations for beginners and he was giving some information on Vectors before he gets into the actual equations. He got to this equation:

I'm real confused, how does he know that dx and dø are both? Why does dø change to dy? What does the equation even mean? Please help I can't continue the video because I'm real confused on his part.

Perhaps for beginners doesn't mean for people who have not yet studied calculus?

I'm real confused, how did he figure that dx and dø are both vectors but the other things are not?

Well that was rather snotty. I figured it out and it was just him not explaining it properly. A forum like this should be welcoming to beginners and not picking fun at their ignorance. If you're not helping then don't reply.
