The basic circular functions are sine, cosine and tangent. Then there are their reciprocals and inverses.

Trigonometry is a mathematical tool that is part of various other forms of mathematics and is used in all sorts of science and engineering; for example, the sine function in trigonometry turns out to be applicable to sine waves that are formed by alternating electrical currents which are used to power your computer which is the basic tool that you use in information technology.

It is a number - in trigonometry or elsewhere.

I have no idea about the signam function.The signum function is odd because sgn(-x) = -sgn(x).

we proceed via the FT of the signum function sgn(t) which is defined as: sgn(t) = 1 for t>0 n -1 for t<0 FT of sgn(t) = 2/jw where w is omega n j is iota(complex) we actually write unit step function in terms of signum fucntion : n the formula to convert unit step in to signum function is u(t) = 1/2 ( 1 + sgn(t) ) As we know the FT of sgn(t) we can easily compute FT of u(t). Hope i answer the question

u(t)-u(-t)=sgn(t)

The Fourier transfer of the signum function, sgn(t) is 2/(iÏ‰), where Ï‰ is the angular frequency (2Ï€f), and i is the imaginary number.

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.

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.
