Can you give me an example of how to express same vector in two cartisean coordinates expression?

And that's not applicable in XYZ expression! That's why it's more useful I always thought it has something to do with direction of movement :D turns out I am wrong Thanks

Doesn't it depend on the X,Y and Z unit vectors? Even if I chose another coordinate system I should express it in terms of the first by (phi)?

Hello there, get the notion of position vectors for a particle, but why we use it instead of cartisean coordinates XYZ? What info does the vectors tell us that the cartisean coordinates doesn't tell us? So if we say a point has coordinates x=2, y=3, z=5 We say its position vector is r=i 2 +...
