Periodic versus non-periodic functions (hw1, ECE301)

Read the instructor's comments here.

periodic function

y = sinx <-- This is very basic periodic fuction.(period time = 2 $\pi$ )

y = cosx <-- This is also very basic periodic function.(period time = 2 $\pi$ )

periodic function means, The funtion repeats over and over with a period time.

non-periodic function mean is opposite of periodic function. simply, The function do not reapeats over again.

$$ y = x^2 $$
