Is signum function a bijective function?
The signum function is defined as follows: f(x) = -1 if x < 0 = 0 if x=0 = 1 if x > 0 It is not one-to-one (bijective) as can be easility seen). f(2)=1 f(3)=1 f(10)=1 and so on.
How do you change an exponential functions to a logarithmic function?
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.
Is function a noun?
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.
Is a function of periodic function periodic?
yes
Every continuous function is integrible but converse is not true every integrable function is not continuous?
That's true. If a function is continuous, it's (Riemman) integrable, but the converse is not true.
Is signum function differentiable?
The signum function is differentiable with derivative 0 everywhere except at 0, where it is not differentiable in the ordinary sense. However, but under the generalised notion of differentiation in distribution theory, the derivative of the signum function is two times the Dirac delta function or twice the unit impulse function.
Is signum function an odd or even function?
both
What is the Laplace transform of the signum function?
2/s
What is the Fourier transform of the signum function?
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.
What is the derivative of the absolute value of x?
The function is called the signum function, or sign(x). It is equal to abs(x)/x
What is the sgn function in trigonometry?
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.
Is signam function even or odd and why?
I have no idea about the signam function.The signum function is odd because sgn(-x) = -sgn(x).
Define the unit step function and signum function bring out the relation between these two functions?
u(t)-u(-t)=sgn(t)
