The understanding of shapes and angles.
The sign function is used to represent the absolute value of a number when used in trigonometry. It is also referred to as the signum function in math.
usually referred as the function COS
Neither, it is a mathematical discipline.
Trigonometry is the study of the relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.
sine, cosine, tangent, cosecant, secant, cotangent.
The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.
The reciprocal of any function f(x) is 1/f(x) provided that f(x) is non-zero. That applies to all relations in mathematics, not just trigonometry.
explain why a function has at most one y-intercept
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.
The period of a trigonometric function, since it depends on the angle of a ray centered in a unit circle, is 2 pi radians or 360 degrees.
