Well the teacher didn't get to this section and teaching myself did not work well lol.. I partly understand to an extent.
The first example goes like
Sketch the graph of the equation r = 3/(2-2sinθ)
Now I doubt you'd be able to graph on this website, but I am wondering how to get to it.
I know that, R= 3/(2-2sinθ) then R=3/2(1-sinθ) therefore R= (3/2) / 1-sinθ
and since a=1, it is a parabola
the next step goes like θ R but how do you work that into a graph?
Second, would be ... Find an equation for the conic section r=1/(1+3sinθ) and i am less confident what to do on this part...
