What means Urban Dictionary?

What means Urban Dictionary?

Originally, Urban Dictionary was intended as a dictionary of slang or cultural words and phrases, not typically found in standard dictionaries, but it is now used to define any word, event, or phrase (including sexually explicit content). …

What does a greater or less than sign with a line under it mean?

It means “greater than OR equal to” some answer. For example, means that x is either greater than 3 OR x equals three; one or the other condition.

How do you use less than sign?

In an inequality, the less-than sign always “points” to the smaller number. Put another way, the “jaws” (the wider section of the symbol) always direct to the larger number.

What are the symbols used in inequalities?

These inequality symbols are: less than (<), greater than (>), less than or equal (≤), greater than or equal (≥) and the not equal symbol (≠).

What is an inequality in maths?

Inequality, In mathematics, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

What does maximum mean in math?

Maximum, In mathematics, a point at which a function’s value is greatest. If the value is greater than or equal to all other function values, it is an absolute maximum.

What does minimum mean in math?

Minimum, in mathematics, point at which the value of a function is less than or equal to the value at any nearby point (local minimum) or at any point (absolute minimum); see extremum.

What is minimum function?

MIN will return the minimum value in a given list of arguments. From a given set of numeric values, it will return the smallest value. Unlike the MINA function, the MIN function ignores numbers, text, and logical values TRUE and FALSE and text values.

Is it a minimum or a maximum?

Minimum means the least you can do of something. For example, if the minimum amount of dollars you must pay for something is seven, then you cannot pay six dollars or less (you must pay at least seven). You can do more than the minimum, but no less. Maximum means the most you can have of something.

What is maximum and minimum value?

A high point is called a maximum (plural maxima). A low point is called a minimum (plural minima). The general word for maximum or minimum is extremum (plural extrema). We say local maximum (or minimum) when there may be higher (or lower) points elsewhere but not nearby.

Can there be 2 absolute maximums?

As this example has shown there can only be a single absolute maximum or absolute minimum value, but they can occur at more than one place in the domain.

What is a relative minimum and maximum?

A relative maximum point is a point where the function changes direction from increasing to decreasing (making that point a “peak” in the graph). Similarly, a relative minimum point is a point where the function changes direction from decreasing to increasing (making that point a “bottom” in the graph).

What is the absolute maximum?

An absolute maximum point is a point where the function obtains its greatest possible value. Similarly, an absolute minimum point is a point where the function obtains its least possible value.

What is a local maximum?

A local maximum, also called a relative maximum, is a maximum within some neighborhood that need not be (but may be) a global maximum. SEE ALSO: Global Maximum, Local Minimum, Maximum, Peano Surface.

What is critical point?

In thermodynamics, a critical point (or critical state) is the end point of a phase equilibrium curve. The most prominent example is the liquid–vapor critical point, the end point of the pressure–temperature curve that designates conditions under which a liquid and its vapor can coexist.

What is a local maximum on a graph?

A local maximum point on a function is a point (x,y) on the graph of the function whose y coordinate is larger than all other y coordinates on the graph at points “close to” (x,y). A local extremum is either a local minimum or a local maximum.

What is a global maximum?

A global maximum, also known as an absolute maximum, the largest overall value of a set, function, etc., over its entire range. It is impossible to construct an algorithm that will find a global maximum for an arbitrary function.

What is a global extrema?

A global extremum, also known as an absolute extremum, is a global minimum or global maximum. It is impossible to construct an algorithm that will find a global extremum for an arbitrary function.

What is an absolute extremum?

Absolute extrema are the largest and smallest the function will ever be and these four points represent the only places in the interval where the absolute extrema can occur. In this example we saw that absolute extrema can and will occur at both endpoints and critical points.

How do you tell if a function has a global maximum?

We say that f has an absolute maximum (or global maximum) at c if f(c) ≥ f(x) for all x in the domain of f. If f has an absolute maximum at c, then f(c) is called the maximum value of f.

How do you maximize a function?

The fundamental idea which makes calculus useful in understanding problems of maximizing and minimizing things is that at a peak of the graph of a function, or at the bottom of a trough, the tangent is horizontal. That is, the derivative f′(xo) is 0 at points xo at which f(xo) is a maximum or a minimum.
