Problem Statement

Let f:SRf:S\to\mathbb{R} be the function from the set of all right triangles into the set of real numbers, defined by f(ΔABC)=hrf(\Delta ABC)=\frac{h}{r}, where hh is the height with respect to the hypotenuse and rr is the inscribed circle's radius. Find the image, Im(f)Im(f), of the function.
