  • Time (t): This is the independent variable, representing the time in seconds.
  • Sine function: This is the mathematical function that describes the relationship between the height and time.

The sine function is a periodic function, meaning it repeats itself at regular intervals. In this case, the sine function has a period of $ 2\pi $, which means it repeats every $ 2\pi $ seconds. The amplitude of the sine function is 7, which represents the maximum height of the windmill blade above the ground.
