WebWe are already very familiar with this. if U is an open subset of Rn and F: U → Rn is a vector field of class C1, then the divergence of F = divF: = ∇ ⋅ F = ∂1F1 + … + ∂nFn. The … WebIn vector calculus, divergence is a vector operator that operates on a vector field, producing a scalar field giving the quantity of the vector field's source at each point. More technically, the divergence represents the volume density of the outward flux of a vector field from an infinitesimal volume around a given point.. As an example, consider air as it is heated or …

This text uses both but favours the USA notation. This text uses both but favours the USA notation. WebCalculation: Let Φ = tan-1 y/x ∴ g r a d Φ = ∇ Φ ∂ Φ ∂ x i ^ + ∂ Φ ∂ y j ^ + ∂ Φ ∂ z k ^ = − y x 2 + y 2 i ^ + x x 2 + y 2 j ^ ⇒ div ( g r a d Φ) = ∂ ∂ x ( − y x 2 + y 2) + ∂ ∂ y ( x x 2 + y 2) = 2 x y ( x 2 + y 2) + − 2 x y ( x 2 + y 2) = 0 ∴ div (grad tan-1 y/x) = 0 The correct answer is Option 2.
