Quadratic functions are essential in the world of mathematics and have a wide range of applications in various fields, such as physics, engineering, and finance. An inverse function can be thought of ...

Inverse functions are used to cancel the effect of one function in mathematics, the inverse function is also known as the anti function and it is defined as “It is a function which can reverse the ...

Abstract: This paper is concerned with obtaining the inverse of polynomial functions using semidefinite programming (SDP). Given a polynomial function and a nominal point at which the Jacobian of the ...

Abstract: The Lambert W function fulfills W(y)· e W(y) = y. With the choice y = log (x) it can hence be applied to invert the function f (x) = x · log(x), which is of some interest in the problems ...
