1. The symbol $t$ is commonly used in mathematics and science to represent **time**. 2. In equations, $t$ often denotes the independent variable that measures the progression of time. 3. For example, in physics, $t$ might represent the time elapsed during an event. 4. In algebra or functions, $t$ can be a parameter or variable that changes, often representing time or another continuous quantity. 5. Understanding what $t$ means depends on the context of the problem, but it usually relates to time or a variable parameter.
