Not so sure about a triangel!
There are, in fact 12 trigonometric functions:
sine, cosine, tangent;
their reciprocals, cosecant, secant and cotangent;
and the inverse functions for all six:
arcsine, arccosine, arctangent, arccosecant, arcsecant and accotangent.
The arc functions are often written with the power -1; that is,
arcsin(y) = sin-1(y).
The six basic functions of trigonometry are the sine, cosine, tangent, cosecant, secant, and cotangent functions. Abbreviated sin, cos, tan, csc, sec, cot.
The basic functions of trigonometry are: sine cosine tangent secant cosecant cotangent
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.
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.
James E. Hall has written: 'Trigonometry; circular functions and their applications' -- subject(s): Plane trigonometry, Trigonometrical 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.
what is 3-D triangel called?
Is the triangel kill alot of poeple?
