The multiplicative reciprocal is the function f(x) = 1/x. It is seductive as it provides a simple function that tapers to a non-zero value (is asymptotic to the x-axis), making it possible to feather effects on a curve or surface. It has a trap as it increases exponentially as its argument approaches zero and is undefined at zero. Thus it is important to set the function range so that zero and values close to it are not included in the function. In general, using this function produces poor results. It is included here to demonstrate that sometimes the function domain choice is crucial. ... more on Design Patterns CA
