WebIn mathematics, an inverse is a function that serves to “undo” another function. That is, if f(x) f ( x) produces y, y, then putting y y into the inverse of f f produces the output x. x. A function f f that has an inverse is called invertible and the inverse is denoted by f−1. f − 1. It is best to illustrate inverses using an arrow diagram: WebA function that consists of its inverse fetches the original value. Example: f (x) = 2x + 5 = y Then, g (y) = (y-5)/2 = x is the inverse of f (x).

"WebJul 7, 2024 · To define an inverse sine (or cosine) function, we must also restrict the domain A to A' such that \sin:A'\to B' is also injective. Such an interval is [-\pi/2,\pi/2]. Then we may define the inverse sine function \sin^ {-1}: [-1,1]\to [-\pi/2,\pi/2], since the sine function is bijective when the domain and codomain are restricted.
