In mathematics, especially functional analysis, a quasitrace is a not necessarily additive tracial functional on a C*-algebra. An additive quasitrace is called a trace. It is a major open problem if every quasitrace is a trace. (Wikipedia).
A graphic and algebraic approach to finding inverse functions. Definition of the Inverse of a Function Let f and g be two functions such that f(g(x)) = x for every x in the domain of g and g(f(x)) = x for all x in the domain of f. Check out http://www.ProfRobBob.com, there you will find

What is the definition of the inverse cosine function
👉 Learn how to evaluate inverse trigonometric functions. The inverse trigonometric functions are used to obtain theta, the angle which yielded the trigonometric function value. It is usually helpful to use the calculator to calculate the inverse trigonometric functions, especially for non-
