Graphing Trigonometry Functions
Find Exact Trigonometry Functionsof Angles
In mathematics, a trigonometric function is a function of an angle. The function values are related to the angles by trigonometric identities. The most familiar trigonometric functions are the sine, cosine, tangent, and their inverses.

Graph Multiple Transformationsof Trigonometry Functions
In mathematics, trigonometry is a branch of mathematics that studies relationships involving lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. Trigonometry is also the foundation of surveying. Trigonometry is most simply associated with planar right-angle triangles (those that have one right angle). Such triangles are the only ones that have a trigonometric ratio associated with their angles. Historically, trigonometry was also called "trigonomics" (from the Greek ???????? trig?non, "triangle" and ?????? metron, "measure"). The term "sine" (Latin sinus) was coined by the Dutch mathematician Willebrord Snellius (1591–1626) and was derived from the word "semijunctus" (half-divided).

Solve Equationsusing Inverse Trigonometry Functions
In mathematics, inverse trigonometric functions are functions that take a trigonometric function as an argument and produce a value in the range of the domain of the original trigonometric function. The inverse trigonometric functions are the inverse functions of the trigonometric functions.

Graph Horizontal Functions
In mathematics, a horizontal function is a function whose graph is a horizontal line. Such functions are important in the study of differential equations, because any horizontal function is the zero solution of a homogeneous linear differential equation.

Graph Vertical Transformations
In mathematics, a transformation is a rule, operation, or a process that maps elements of one set (the domain) to another set (the range). For example, a linear transformation is a rule that takes a vector in a space and transforms it to another vector also in that space. A vertical transformation is a transformation in which the output is a scalar multiple of the input.

Graphing CSCSECCOT Functions
In mathematics, a function is a relation between a set of inputs and a set of permissible outputs with the property that each input is related to exactly one output. An example is the function that relates each real number x to its square x^2. The output of a function f corresponding to an input x is denoted by f(x). A function whose domain is a subset of the real numbers is called a "real-valued function". A function from a set X to a set Y is a subset of the Cartesian product X × Y that preserves the ordering, that is, if "x" is in "f" then so is "y" for any "y" in Y. Such a function is called "continuous" if the preimage of every neighborhood of a point "x" in X is a neighborhood of "f"("x") in Y. A function from the real numbers to the real numbers is called a "continuous function". However, most commonly encountered functions in calculus are "discontinuous", which means that they are defined only on a subset of the real numbers.

Graphing Cosine Functions
In mathematics, the cosine function is a trigonometric function that measures an angle's size in degrees. The term "cosine" comes from the Latin word cosinus, which means "the adjacent side". The cosine of an angle is denoted by the symbol or cos. In terms of the standard unit circle, the cosine can be defined as the ratio of the adjacent leg to the hypotenuse of a right triangle, or the ratio of the adjacent side to the hypotenuse.

Graphing Sine Functions
In mathematics, the sine function or sin is a trigonometric function, defined for any angle in the interval (0,2?). It tells us how much the function changes when the angle changes by. It is also known as the "sinus" function in the old German notation.

Graphing Tangent Functions
In mathematics, the tangent function (or tangent) is a function that defines the slope of a straight line, or line segment, at any point along it. The slope of a line is defined as the ratio of the "vertical change" to the "horizontal change" between any two distinct points on the line. The slope of a straight line is constant, and equal to its value at the point where the line is defined, but the slope of a line segment is not constant, and is usually different from the slope of the line at either end of the line segment.

Periodand Amplitudeof Trigonometry Functions
In mathematics, the period of a periodic function is the length of its repeating pattern. The period of a periodic function is the number of full periods of the function. The period of the sine function is the number of radians through which its graph rotates. The amplitude of a periodic function is the maximum distance of the graph from the x-axis.

Periodand Amplitudeof Trigonometry Functions - Example 1
The period of a periodic function is the time elapsed for a complete cycle. In trigonometry, the period, usually denoted by T, is the length of a circular arc in the unit circle, which is the inverse function of the sine function. The period of a periodic function is the time required for the function to repeat itself. For example, if the period of a function is 2?, then the function repeats itself after every 2? units of time. The inverse function of the sine function is the circular function, which is defined as the length of the arc of the unit circle between the point (1,0) and the point (x,y). The period of a function is a measure of the frequency of the function.

A trigonometric function is a function of an angle. The angle may be in radians or in degrees. The trigonometric functions are commonly defined for angles in the range –90° to +90°. The commonly-used trigonometric functions are sine (sin), cosine (cos), tangent (tan), cotangent (cotan), secant (sech), and cosecant (cosech). The inverse trigonometric functions are the arcsine (arcsin), arccosine (arccos), arctangent (arctan), arccotangent (arccotan), arcsecant (arccosec), and arc cosecant (arccosech).
