Fill the table (for 1 period) and label each graphs with appropriate scale (for 2 periods):

C(x) = cos(2pix)

2pix= 0 ; x = 0 ; C(0) = cos(0) =1

2pix= pi/2 ; x = 1/4 ; C(pi/2) = cos(pi/2) = 0

2pix = pi ; x = 1/2 ; C(pi) = cospi = -1

2pix = 3pi/2 ; x= 3/4 ; C(3pi/2) = cos(3pi/2) = 0

2pix = 2pi ; x= 1 ;C(2pi) = cos2pi = 1
