Question 742970
find an interval for theta for which the graph is traced only once 
r=2sin(3theta/2) = 2sin((3/2)theta)
Form: r = asin(bx) + c
-----
That would be one period.
Period = (2pi/b) = (2pi/(3/2)) = (4/3)pi

==================
a-0<=theta<=pie/3
b-0<=theta<=pie
c-0<=theta<=4pie
d-0<=theta<=4pie/3
e- -2pie<=theta<=2pie
