For r = 3cos(2(theta + pi/12)), which first-petal data should a sketcher use?
A
A petal is centered at theta=pi/12 and has endpoints theta=-pi/6 and theta=pi/3
B
A petal is centered at theta=-pi/12 and has endpoints theta=-pi/3 and theta=pi/6
C
A petal is centered at theta=0 and has endpoints theta=-pi/4 and theta=pi/4
D
There are no petals because the angle is shifted
