vanish 

verb (vanish, es)
 To become invisible or move out of view unnoticed.

(Mathematics) To become equal to zero.

The function f(x)=x^2 vanishes at x=0.

 Adjective, variable
 something whose value may be dictated or discovered

There are several variables to consider here.

(mathematics) a quantity that may assume any one of a set of values

(mathematics) a symbol representing a variable

(complang) a named memory location in which a program can store intermediate results and from which it can read it them

adjective

vector function 

noun
(mathematics) Any function whose range is ndimensional

vector product 

noun

(vector) a vector with the size given by the product of two vectors computed as the product of the magnitudes of the vectors and the sine of the angle between their directions, and directed perpendicular to the given two vectors, with positive orientation.

vector space 

noun

(maths) A type of set of vectors that satisfies a specific group of constraints.
A vector space is a set of vectors which can be linear combination, linearly combined.vector space over the fieldF
(linear algebra) A set V, whose elements are called "vectors", together with a binary operation + forming a module (V,+), and a set F^{
of bilinear unary functions f
:V→V, each of which corresponds to a "scalar" element f of a field F, such that the composition of elements of F
corresponds isomorphically to multiplication of elements of F, and such that for any vector v, 1
(v) = v.
}
 Any field <math>\mathbb{F}</math> is a onedimensional vector space over itself.

If <math>\mathbb{V}</math> is a vector space over <math>\mathbb{F}</math> and S is any set, then <math>\mathbb{V}^S={f, f:S\rightarrow \mathbb{V} \}</math> is a vector space over <math>\mathbb{F}</math>, and <math> \mbox{dim} ( \mathbb{V}^S ) = \mbox{card}(S) \, \mbox{dim} (\mathbb{V})</math>.
 If <math>\mathbb{V}</math> is a vector space over <math>\mathbb{F}</math> then any closed subset of <math>\mathbb{V}</math> is also a vector space over <math>\mathbb{F}</math>.
 The above three rules suffice to construct all vector spaces.
