Periodic Functions
A periodic function is a function which repeats over a period of time. A good example of periodic functions are:
- $ \,y = sin(t) $
As you can see, this function repeats itself with a period of $ 2\pi $
- $ \,y = cos(t) $
As you can see, this function repeats itself with a period of $ 2\pi $
Non-Periodic Functions
Non periodic functions don't repeat. A good example of non-periodic functions are:
- $ \,y = x^2 $
- $ \,y = e^x $
