Cách sử dụng
The word 'constant' means something that remains the same and doesn't change. It can be used to describe something that is always present or happening, without interruption. For example, if someone complains about the constant noise in their neighborhood, they are referring to a sound that is always there and doesn't go away. In math, ‘constant’ is used to describe a fixed value that doesn't change in an equation. If someone says that they have a constant headache, they mean that they have been experiencing it for a long time, and it hasn't stopped.
