- Affine space : Collection of points, none of which is special; an n-dimensional vector belongs to any pair of points.
- Curl : A vector operator that describes the rotation of a vector field.
- Dirac delta function : Sharply peaked function, generalization of the Kronecker delta; a distribution that maps a regular function onto a single function value.
- Euler angles : three rotation angles that describe any rotation of a 3-dimensional object.
- Jacobian : Determinant of the matrix whose ith row lists all the first-order partial derivatives of the function ƒi(x1, x2, …, xn).
- Line (geometry) : (or straight line) In elementary geometry, a maximal infinite curve providing the shortest connection between any two of its points.
- Linear algebra : Branch of mathematics that deals with the theory of systems of linear equations, matrices, vector spaces, determinants, and linear transformations.
- Momentum : mass of a particle times its velocity (a vector).
- Multipole expansion of electric field : an expansion in terms of powers of 1/R of an electric potential outside a charge distribution; R is the distance of a point outside to a point inside the charge distribution.
- Plane (geometry) : In elementary geometry, a flat surface that entirely contains all straight lines passing through two of its points.
- Point (geometry) : An object that has a position but no length, breadth or depth.
- Polar coordinates : Two numbers—a distance and an angle—that specify the position of a point on a plane.
- Polarizability : The ease by which a charge-distribution polarizes; describes the amount of charge separation caused by an electric field.
- Relative permittivity : A factor describing the polarizability of a material or medium as a proportionality between an electric displacement and an electric field in a dielectric.
- René Descartes : French 17th-century philosopher, mathematician and scientist, author of the Discourse on Method.
- Right-hand rule : Rule for the direction of the vector describing a cross product, a torque, or an angular momentum.
- Rotation matrix : a 3×3 proper (unit determinant) orthogonal (orthonormal rows and columns) matrix
- Sine : In a right triangle, the ratio of the length of the side opposite an acute angle (less than 90 degrees) and the length of the hypotenuse.
- Spherical harmonics : A series of harmonic basis functions that can be used to describe the boundary of objects with spherical topology.
- Spherical polar coordinates : Angular coordinates on a sphere: longitude angle φ, colatitude angle θ
