WebNov 16, 2024 · Now that we’ve seen a couple of vector fields let’s notice that we’ve already seen a vector field function. In the second chapter we looked at the gradient vector. Recall that given a function f (x,y,z) f ( x, y, z) the gradient vector is defined by, ∇f = f x,f y,f z ∇ f = f x, f y, f z . This is a vector field and is often called a ... WebVector Operators: Grad, Div and Curl In the ﬁrst lecture of the second part of this course we move more to consider properties of ﬁelds. We introduce three ﬁeld operators which reveal interesting collective ﬁeld properties, viz. the gradient of a scalar ﬁeld, the divergence of a vector ﬁeld, and the curl of a vector ﬁeld.
