👉 The term "diapason" is often used in mathematics and physics to describe a point where two functions or quantities have different values. It is named after the Greek word "dia", meaning "one" or "two," which can be interpreted as "separation." When these two points are at a certain distance from each other, they form a diapason. For example, consider two functions f(x) and g(x), both of which have the same value. If we define a
