Del operator

The del operator ∇ is an operator commonly used in vector calculus to find derivatives in higher dimensions, When applied to a function of one independent variable, it yields the derivative,For multidimensional scalar functions, it yields the gradient,If either dotted or crossed with a vector field, it produces divergence or curl, respectively, which are the vector equivalents of

Dirac delta function

In mathematics, the Dirac delta function δ function, also known as the unit impulse symbol, is a generalized function or distribution over the real numbers, whose value is zero everywhere except at zero, and whose integral over the entire real line is equal to one, It can also be interpreted as a linear functional that maps every function to its value at zero, or as the weak limit of a
