since `r sin theta =y` and `r=(1)/(sin theta),y =1` The domain of `r=(1)/(sin theta)` is all real `theta` that are not multiples of `pi`
Thus `r=(1)/(sin theta)` is the equation of a horizontal line with holes in it at multipls of `pi` one unit above the x axis
Both `r=2` and `r=(1)/(sin theta)` are examples of polar function such function can be graphed on a graphing calculator by using POLAR mode Enter 2 in to `r_(1)` and graph using ZOOM 6 the standard window
Although the graph is accurate for the scale given the shape looks like that of an ellipse not a circle this is beacuse the standard screen has a scale on the x xis that is larger than that on the y axis resulting in a distroted graph the graph below is obtained by using the ZOON Zsquare command
