Question

How do you graph `r = 2·sin(theta)`?

Answer 1

I use the free on-line graphing calculator www.desmos.com/calculator but you may want use polar graph paper and create a table.

Explanation:

Here is the graph that the Desmos creates:

The following is a sample of a table:

#{:(r, theta), (0,0), (1,pi/6), (sqrt2,pi/4), (sqrt3,pi/3), (2,pi/2), (sqrt3,(2pi)/3), (sqrt2,(3pi)/4), (1,(5pi)/6), (0,pi):}#
