Hello, i need urgent help please. I can't figure this out. It says to use the desmos graphing tool. Please help with the questions as well as all 8 radian points

Use the Cosine Graphing Tool to create this cardioid. r = 4 - 2Cos(q) The cardioid lies completely in between two BLUE circles: 0 Ers 2pi The portion of the graph between the RED circles is where: Ers Scrolling n forward, each shaded sector has size 1/ of a full period with each shaded sector radian measure p/ Scrolling S forward from zero, the shape begins (and ends) at the first point ( r , q ) = ( Enter the next 8 points in order, using radians for angles. ( Enter 3p/2 as 3pi/2 with no spaces. ) Point # ( r, q) 1 already answered above 2
