In algebra, we use variables like x, y, and z to represent unknown values. Expressions are combinations of variables and numbers, while equations equate two expressions. Variables can take on different values depending on the context, and we can evaluate expressions by substituting values for the variables. Created by Sal Khan.These are symbols that is most commonly used in linear algebra. If x=y, x and y represent the same value or thing. If x≈y, x and y are almost equal. If x≠y, x and y do not represent the same value or thing. If x<y, x is less than y. If x>y, x is greater than y. If x≪y, x is much less than y.Z is used to signify the atomic number or proton number of an atom. Z = # of protons of an atom. A is used to signify the atomic mass number (also known as atomic mass or atomic weight) of an atom. A = # protons + # neutrons. A and Z are integer values. When the actual mass of an atom is expressed in amu ( atomic mass units) or g/mol then the ...Constant Functions. Another special type of linear function is the Constant Function ... it is a horizontal line: f(x) = C. No matter what value of "x", f(x) is always equal to some constant value.

Endpoints are also called boundary points. A circle with one point deleted is also an example of a manifold. Think of a torn elastic band. By straightening out the elastic band we see that this manifold is really the same as an open interval.more. The dependent variable is the one that depends on the value of some other number. If, say, y = x+3, then the value y can have depends on what the value of x is. Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5.

3. Departing a little from the other very good answers here. Strictly speaking, nabla is the name of the typographical glyph, the upside down triangle: just a symbol on paper, meaning whatever the author intends it to mean. The name comes from the glyph's resemblance to an old fashioned harp.

Fundamental set concepts. In naive set theory, a set is a collection of objects (called members or elements) that is regarded as being a single object. To indicate that an object x is a member of a set A one writes x ∊ A, while x ∉ A indicates that x is not a member of A. A set may be defined by a membership rule (formula) or by listing its ...Z.

The symbol derives from the German word Zahl , meaning "number" (Dummit and Foote 1998, p. 1), and first appeared in Bourbaki's Algèbre (reprinted as Bourbaki 1998, p. 671).These symbols allow us to represent a wide range of logical concepts, such as “and,” “or,” “if-then,” and “if and only if.”. Knowing these logic symbols is useful because it allows us to more easily understand and communicate logical concepts. Below we have listed a few common ones. Symbol. Name. Meaning/Definition. Example.A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula.Just as in a three-dimensional coordinate grid in math class, there is an origin point (0, 0, 0) where all three axes meet, and the coordinates X, Y, and Z represent distances from this point.
