Because any angle increased by k*2pi radians (= k*360 degrees) where k is an integer, is, effectively, the same angle. This implies that f(x + 2kpi) = f(x) for any angle x and any trig function f. This gives f a maximum period of 2pi radians.
The six basic functions of trigonometry are the sine, cosine, tangent, cosecant, secant, and cotangent functions. Abbreviated sin, cos, tan, csc, sec, cot.
The principles of trigonometry revolve around the relationships between the angles and sides of triangles, particularly right triangles. Key concepts include the sine, cosine, and tangent functions, which relate the angles to the ratios of the lengths of the sides. Additionally, the Pythagorean theorem establishes a fundamental relationship between the sides of a right triangle. Trigonometry is also essential in studying periodic phenomena, such as waves and oscillations, through its functions and identities.
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.

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.
Trigonometry (from Greek trigōnon "triangle" + metron "measure") is a branch of mathematics that studies triangles, particularly right triangles. Trigonometry deals with relationships between the sides and the angles of triangles, and with trigonometric functions, which describe those relationships and angles in general, and the motion of waves such as sound and light waves. There are an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems. The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.

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.
What are the four functions of a periodic table?
because sine & cosine functions are periodic.
