First, calculate the period.

omega=(2pi)/B=(2pi)/(1/3)=((2pi)/1)*(3/1)=6piω=2πB=2π13=(2π1)(31)=6π

Break up 6pi6π into fourth by dividing by 44.

(6pi)/(4)=(3pi)/(2)6π4=3π2

0,(3pi)/(2),3pi,(9pi)/2,6pi ->x0,3π2,3π,9π2,6πx-values

These xx values correspond to ...

sin(0)=0sin(0)=0

sin((pi)/(2))=1sin(π2)=1

sin(pi)=0sin(π)=0

sin((3pi)/2)=-1sin(3π2)=1

sin(2pi)=0sin(2π)=0

Enter the function using the Y= button

Press the WINDOW button.
Enter the Xmin of 00 and Xmax of 6pi6π.
The calculator converts 6pi6π to its decimal equivalent.
