A line that cuts across two or more (usually parallel) lines. In the figure below, the line AB is transversal. It cuts across the parallel lines PQ and RS. If it crosses the parallel lines at right angles it is called a perpendicular transversal.
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted. In Euclidean geometry any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. A
two-dimensional Euclidean space).
In geometry, a triangular prism is a
three-sided prism / it is a polyhedron made
of a triangular base, a translated copy, and 3 faces joining corresponding sides.
The trigonometric functions (also called circular functions, angle functions or goniometric functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. The most familiar trigonometric functions are the sine, cosine,
and tangent.
Trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables where both sides of the equality are defined. Geometrically, these are identities involving certain functions of one or more angles
The definition of a trinomial is a math equation that has three terms which are connected by plus or minus notations. An example of trinomial is 6x squared + 3x + 5. Trinomial means the scientific name of a plant. An example of a trinomial is a name
which includes the genus, species and the variety.
Refers to the absence of an upper or lower bound for a set, sequence, function, or mathematical object. If a set or function is unbounded, it means that there is no finite
value that serves as an upper or lower limit for its elements or values.
In mathematics, the method of undetermined coefficients is an approach to finding a particular solution to certain
nonhomogeneous ordinary differential equations and recurrence relations.
Union of two sets. The union of two sets is everything in both sets. For example, if you have the set {3,4,5} and the set {5,6,7}, then the union of these two sets is {3,4,5,6,7}.
The symbol for union is a capital U.
In mathematics and logic, the phrase "there
is one and only one" is used to indicate that exactly one object with a certain property exists. In mathematical logic, this sort of quantification is known as uniqueness quantification or unique existential quantification.
In set theory, a universal set is a set which contains all objects, including itself. In set theory as usually formulated, the conception of a universal set leads to a paradox and is consequently not allowed. However, some non-standard variants of set theory include
a universal set.
In mathematics, especially in order theory, an upper bound of a subset S of some partially ordered set is an element of K which is greater than or equal to every
element of S.
A variable is a quantity that may change within the context of a mathematical problem or experiment. The letters, and are common generic symbols used for variables. Sometimes, we will choose a letter that reminds us of the quantity it represents, such as for time, for voltage, or
for bacteria.
A vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the
direction.
Are straight lines of the equation, toward which a function f(x) approaches infinitesimally closely, but never reaches the line, as f(x) increases without bound. For these values of x, the function is either
unbounded or is undefined.
Volume is the measure of the amount of space inside of a solid figure, like a cube, ball, cylinder or pyramid. Its units are always "cubic", that is, the number of little element cubes that fit inside the figure.
Wavelength is the distance between two identical adjacent points in a wave. It is typically measured between two easily identifiable points, such as two adjacent crests or troughs in a waveform.
Length, when referring to measurement in one dimension (as in the length of a line segment or a or a piece of string), has a specialized meaning. So, does height when
it is used in conjunction with base.
A zero, also sometimes called a root, of a real-, complex- or generally vector-valued function is a member of the domain of such
that vanishes at / that is, is a solution of the equation. In other words, a "zero" of a function is an input value that produces an output of zero.
