First, calculate the period.

omega=(2pi)/B=(2pi)/(1/2)=((2pi)/1)*(2/1)=4piω=2πB=2π12=(2π1)(21)=4π

Break up 6pi6π into fourth by dividing by 44.

(4pi)/(4)=pi4π4=π

0,pi,2pi,3pi,4pi ->x0,π,2π,3π,4πx-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 4pi4π.
The calculator converts 4pi4π to its decimal equivalent.
