\nabla f=\left(\frac{\partial f}{\partial x_1},\ldots,\frac{\partial f}{\partial x_n}\right)Variables
- f: scalar field
- xᵢ: coordinate variables
How to use this formula
Forms a vector of partial derivatives of a scalar field.
Important notes
- The gradient points in the direction of steepest increase.
Quick example
For f=x²+y², ∇f=(2x,2y).
Applicability, worked calculation, and verification
Assumptions and domain checks
- The gradient points in the direction of steepest increase.
- For the Gradient, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
- The function must satisfy the differentiability, continuity, or integrability conditions required by the operation being used.
Worked example
For f=x²+y², ∇f=(2x,2y).
Common mistakes
- When copying Gradient, 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.
