Use the Cosine Graphing Tool to create this shape. r = 9+ 8Cos(q/2) Setting w = 1 , g = 1 , z=0 , j=1 , k=1 turning off the y-axis and scrolling S we see that one waveform has full period and quarter period Scrolling n forward, each shaded sector on the second waveform has size p/ Scrolling S forward, enter these 9 points in order. Continue using simplified positive radians for angles, entering 8p/4 or 6p/3 as 2pi with no spaces. ) Point # ( r , q )
