Gradient Calculator
Compute the gradient vector ∇f of a multivariable function f(x, y, ...).
Gradient Vector:
∇f = (∂f/∂x₁, ∂f/∂x₂, ..., ∂f/∂xₙ)
Where each component is the partial derivative of f with respect to the corresponding variable.
Enter variables in standard notation, separated by commas. Supports multivariable functions using standard math notation.
