Constant
A term that does not contain a variable.
In mathematics, a constant is a value that does not change. It is fixed and remains the same throughout a given problem, equation or experiment. Some examples of common constants in mathematics include:
– The mathematical constant pi (π) which is approximately 3.14159. This constant represents the ratio of the circumference of a circle to its diameter. It is used extensively in geometry, trigonometry and calculus.
– The mathematical constant e which is approximately 2.71828. This constant is the base of the natural logarithm and is used extensively in calculus and complex analysis.
– The speed of light (c) is a physical constant that represents the speed at which photons travel through empty space. It is approximately 299,792,458 meters per second and is used in physics and other physical sciences.
Other examples of constants include the gravitational constant, the gas constant, and various mathematical and physical constants that are specific to certain fields of study. Constants are often represented by symbols or letters, such as the Greek letter pi (π) or the letter c for the speed of light.
