A constant, sometimes also called a "mathematical constant," is any well-defined genuine number i beg your pardon is substantially interesting in part way. In this work, the hatchet "constant" is usually reserved for genuine nonintegral numbers of interest, when "number" is provided to refer to interesting integers (e.g., Brun"s constant, yet beast number). However, in contexts together as direct combination, the ax "constant" is generally used to median "scalar" or "real number," and also need not exclude integer values.
You are watching: What is a constant in an equation
A function, equation, etc., is claimed to "be constant" (or be a consistent function) if it always assumes the same value elevation of how its parameters are varied.
Certain constants are recognized to many decimal digits and recur throughout many diverse areas of mathematics, frequently in unexpected and surprising places (e.g., pi, e, and to part extent, the Euler-Mascheroni consistent
The mathematician Glaisher remarked, "No doubt the desire to attain the values of these amounts to a good many figures is additionally partly because of the reality that many of lock are amazing in themselves; because that
