SUMMARY
The inverse of sinc(x), defined as sinc(x) = sin(x)/x, cannot be expressed in terms of elementary functions. While the sine function has an inverse when restricted to the interval [0, π], the inverse of sinc(x) does not yield a simple functional form. To find x in terms of a, where sinc(x) = a, one would typically resort to graphical methods or numerical solutions, as the equation xy = sin(x) cannot be solved algebraically for x.
