It is trigonometry.
Trigonometry is essential to the study of higher mathematics (calculus) and to the understanding of many scientific and engineering principles. Trigonometry and calculus can be used to model many shapes, motions, and functions in daily life.
Trigonometry originated in ancient times, and was closely related to geometry. It was useful especially in astronomy and navigation. Later on trigonometry led to the idea of sine waves as fundamental for analysing vibrations of all kinds. Trigonometric functions occur in the theory of complex numbers, and now the trig functions turn up in many places in mathematics and its applications, from optics to the theory of alternating current in electrical engineering. The uses of the trig functions have spread far beyond the original ones.
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions and their inverses. The link below demonstrates the relationship between functions.
Calculus is the study of instantaneous and cumulitive growths of functions with respect to two or more variables. Trigonometry is the study of angles, specifically in triangles.
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
The six basic functions of trigonometry are the sine, cosine, tangent, cosecant, secant, and cotangent functions. Abbreviated sin, cos, tan, csc, sec, cot.
There are two types of functions in trigonometry: there are functions that are mappings from angles to real numbers, and there are functions that are mappings from real numbers to angles. In some cases, the domains or ranges of the functions need to be restricted.
"IS" not "are"! The numerical study of angles and their functions.

Not specifically trigonometry, but functions in general. As a general rule, functions must be evaluated before using the results in other parts of the calcuation.
Trigonometry functions are used to work out the various properties of triangles.
It is trigonometry.
Trigonometry is the study of the relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.
The same as in any other math class. All functions are relations but all relations are not functions. A function must have only one 'answer' in the range for each value of the domain. Relations are just pairing of numbers with no such restriction on the range.
They are organised into categories. Those categories are: Database functions Date and time functions Engineering functions Financial functions Information functions Logical functions Lookup and reference functions Math and trigonometry functions Statistical functions Text functions External functions Cube functions
A way to remember the definitions of the three most common trigonometry functions: sin, cos and tan. Used as a memory aid for the definitions of the three common trigonometry functions sine, cosine and tangent.
