WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. The formula for divergence is. div v ⃗ = ∇ ⋅ v ⃗ = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯. Web2D Vector Field Grapher. Conic Sections: Parabola and Focus. example
