Chapter 4, Problem 16CT

To determine

To graph:Sketch the graph of function and find its period.

Explanation of Solution

Given information:

The function is

  $y=\sin 2\pi x\text{ + 2cos}\pi x$

Graph:

The graph of $y=\sin 2\pi x\text{ + 2cos}\pi x$ is given below.

  

Interpretation:

The function $y=\sin 2\pi x\text{ + 2cos}\pi x$ is periodic with period 2.
