## Constant

### In mathematics, a constant refers to a fixed value that does not change

In mathematics, a constant refers to a fixed value that does not change. It is a specific number or quantity that remains unchanged throughout a particular problem, equation, or mathematical expression.

One common example of a constant is the number pi (π), which is approximately equal to 3.14159. Pi is a constant because its value does not change, regardless of the context or the specific mathematical calculation being performed. Another example is the speed of light in a vacuum, which is a fundamental constant in physics and is denoted by the symbol ‘c’. Its value is approximately 299,792,458 meters per second.

Constants are often denoted by specific symbols or letters, such as ‘c’ for the speed of light or ‘G’ for the gravitational constant. These symbols are used to represent their respective fixed values and are used in mathematical equations to provide consistency and accuracy in calculations.

It is important to note that constants are different from variables, which can vary or change their value. Constants are always fixed, while variables can take on different values depending on the circumstances and the specific problem being solved.
