Lesson 5: Periodic Function
(1) What is the meaning of "periodic"?
A periodic function f is one that repeats its values in regular intervals of length I. (I.e. its graph repeats itself every interval of length I.
I is also known as the "period" of the function.
f (x) = sin x is a periodic function with a period .
A function g is defined as follows:
Sketch the graph of g for and find the value of g(17).
