Concept explainers
The Sawtooth Curve An oscilloscope often displays a sawtooth curve. This curve can be approximated by sinusoidal curves of varying periods and amplitudes.
(a) Use a graphing utility to graph the following function, which can be used to approximate the sawtooth curve.(a) Use a graphing utility to graph the following function, which can be used to approximate the sawtooth curve.
(b) A better approximation to the sawtooth curve is given by
Use a graphing utility to graph this function for and compare the result to the graph obtained in part (a).

Explanation of Solution
Given:
An oscilloscope often displays a sawtooth curve.This curve can be approximated by sinusoidal curves of varying periods and amplitudes.
Calculation:
Graph of
b.
We see that the graph has added more bumps and it makes them appear like a saw tooth.
c.
Compared to previous graphs we see that the graph has added bumps at every 1/4th and it makes them appear like a saw tooth.
d. from , and we see that the next approximation is
