Show a function is well defined
WebMar 24, 2024 · A function from A to B is a rule that assigns to every element of A a unique element in B. We call A the domain, and B the codomain, of the function. If the function is called f, we write f: A → B. Given x ∈ A, its associated element in B is called its image under f. WebApr 25, 2024 · If this holds, then the mapping ϕ is well-defined . The terminology is misleading, as ϕ cannot be defined at all if the condition is not met. What this means is: if we want to define a mapping from a quotient set to any other set, then all the individual elements of each equivalence class in the domain must map to the same element in the …

WebThis definition a priori depends on the choice of the parametrization 1. The point of this exercise is to show that in fact it does not. Hence, the integral of a function over a curve C is well-defined. Consider ñ another parametrization of C.

WebApr 21, 2010 · Apr 20, 2010. #1. Hi. I am trying to show that for f belonging to L^2 (-pi;pi) the integral that defines the complex Fourier Coefficients is well defined. In other words what I need to show is that. int_from -pi to pi ( f (x)*exp (-i*k*x) dx) < infinity (limited) I was thinking that since f belongs to L^2 (-pi;pi) then the integral of this will ...

To show that a function is injective, you show that if f (x) = f (y), then x = y. If you think back to …
WebFeb 8, 2024 · A bijective function is also an invertible function. Knowing that a bijective function is both one-to-one and onto, this means that each output value has exactly one pre-image, which allows us to find an inverse function as noted by Whitman College.
