Curl of a scalar times a vector
WebNov 8, 2024 · Note that a scalar product of a vector with itself is the square of the magnitude of that vector: (1.2.3) A → ⋅ A → = A 2 cos 0 = A 2 It should be immediately clear what the scalar products of the unit vectors are. They have unit length, so a scalar product of a unit vector with itself is just 1. (1.2.4) i ^ ⋅ i ^ = j ^ ⋅ j ^ = k ^ ⋅ k ^ = 1 WebCurl identity: ∇×(fA) = (∇f)×A + f(∇×A), where A is a vector field and f is a scalar function. These vector identities are important tools in many areas of mathematics, physics, and engineering, and they can be used to simplify calculations and derive new relationships.

WebDivergence is a scalar, that is, a single number, while curl is itself a vector. The magnitude of the curl measures how much the fluid is swirling, the direction indicates the axis around which it tends to swirl. These ideas are somewhat subtle in practice, and are beyond the scope of this course.
