Honey, the signum function is about as bijective as a one-way street. It sure ain't bijective, because it maps every non-zero number to 1, completely ignoring the negative numbers. So, in short, signum function is not bijective, it's as one-sided as a bad Tinder date.
If y is an exponential function of x then x is a logarithmic function of y - so to change from an exponential function to a logarithmic function, change the subject of the function from one variable to the other.
Yes, the word 'function' is a noun (function, functions) as well as a verb (function, functions, functioning, functioned). Examples: Noun: The function of the receptionist is to greet visitors and answer incoming calls. Verb: You function as the intermediary between the public and the staff.

That's true. If a function is continuous, it's (Riemman) integrable, but the converse is not true.
The signum function, also known as the sign function, is not differentiable at zero. This is because the derivative of the signum function is not defined at zero due to a sharp corner or discontinuity at that point. In mathematical terms, the signum function has a derivative of zero for all values except at zero, where it is undefined. Therefore, the signum function is not differentiable at zero.

The Fourier transfer of the signum function, sgn(t) is 2/(iω), where ω is the angular frequency (2πf), and i is the imaginary number.
The function is called the signum function, or sign(x). It is equal to abs(x)/x
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.
I have no idea about the signam function.The signum function is odd because sgn(-x) = -sgn(x).
u(t)-u(-t)=sgn(t)
