WebThe gradient is a vector associated with a scalar field--a real-valued function of several real variables. Usually, a tangent vector is associated with a curve--a vector-valued function of a single variable. Is this the kind of tangent vector you're referring to? – Muphrid Jan 30, 2013 at 22:55 3 Webthe gradient transforms as a vector under rotations I can see how to show these things mathematically, but I'd like to gain some intuition about what it means to "transform as a" vector or scalar. I have found definitions, but none using notation consistent with the Griffiths book, so I was hoping for some confirmation.
