## Volume

In geometry, the volume is defined as the measure of space occupied by a three-dimensional body. The volume of a three-dimensional body is a numerical characteristic of the body; in the simplest …

## Distance

Distance formula.

## Position

In order to describe the motion of an object, you must first be able to describe its position (where it is at any particular time). More precisely, you need to specify its …

## Displacement

The displacement of an object is defined as the vector distance from some initial point to a final point. This change in position is known as displacement. The word “displacement” implies that …

## Monomial

It is defined monomial as a literal algebraic expression, consisting of a numerical part (coefficient) and a literal part among which only multiplication and exponentiation operations appear; for example: $\dfrac{1}{2}x;\;7x^2y;\;-9x^n$ The monomial …

## Statistical hypothesis testing

Hypothesis testing is a branch of statistics that tries to evaluate the reliability of a hypothesis through the results of an experiment or a series of observations. The hypotheses considered can …

## Exponentiation

Exponentiation is one of the mathematical operations that replace multiple multiplications between equal numbers or variables, simplifying both writing and processing. If the exponent is greater than 1, the power is …

## Isometry

In mathematics, an isometry (from the Greek ἴσος, isos, which means equal | called also congruence, or congruent transformation) is a notion that generalizes that of rigid movement of an object or a geometric …

## Probability

Probability distribution.

## Inequation

The inequations, unlike the equations, are inequalities between monomials, or polynomials, for which we seek the solution of one or more literal variables, called unknowns (as for the equations). Some examples of inequations are: …
