Laplace's equation is defined as the divergence of the gradient of a function set equal to zero. This is also written using the Laplace Operator or Laplacian (∇² or Δ). The gradient is the vector differential operator which gives a vector of the partial derivatives of a function. Partial derivatives are derivatives of a multivariable function while holding the other variables constant. The divergence is written as the dot product of the del operator with a vector field, and gives a scalar that is the sum of the partial derivatives of the field's components. The divergence of the gradient of a function gives the sum of second partial derivatives. The gradient gives the direction and rate of fastest inc
