👉 In mathematics, "interspecial" refers to a set of related special functions that are defined on a common domain and have similar or overlapping domains. These functions are often used in physics, engineering, and other fields where they serve as fundamental building blocks for solutions involving multiple variables. For example, consider the following function: $$ f(x) = \frac{1}{x} $$ This function is an example of an "interspecial" function because it has a common domain (all real numbers
