Topic: Polar Coordinates
1. Identify the polar coordinates for each value in the table below and use this to graph
the equation of r = 3 sin 20
Symmetry hint: see if the equation is true for the following:
replace (r, 0) with (r, 180° - 0) or (-r, -0)
replace (r, 0) with (-r, 180°-0) or (r, -0)
replace (r, 0) with (r, 180° + 0) or (-r, 0)
1. the line 090°:
2. the polar axis:
the pole:
