\nabla\cdot\mathbf F=\sum_i\frac{\partial F_i}{\partial x_i}Variables
- F: vector field
- Fᵢ: components
How to use this formula
Measures local source or sink strength of a vector field.
Important notes
- Coordinate-specific forms differ outside Cartesian coordinates.
Quick example
For F=(x,y), divergence is 2.
Applicability, worked calculation, and verification
Assumptions and domain checks
- Coordinate-specific forms differ outside Cartesian coordinates.
- For the Divergence, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
- For the Divergence, the index variable, lower bound, upper bound, and any empty-sum or empty-product convention must be clear.
- Preserve matrix order and verify dimension compatibility; multiplication and inversion are not generally commutative or always defined.
Worked example
For F=(x,y), divergence is 2.
Common mistakes
- When copying Divergence, keep the complete numerator and denominator grouped; a missing brace or parenthesis changes the result.
- Do not apply a differentiation or integration rule outside its domain or omit endpoint, continuity, or constant-of-integration checks.
