translate this polar equation into a rectangular form:
rsin(2theta)=sin(theta)
My answer:
r2sin(theta)cos(theta)=sin(theta)
2rcos(theta)=1
2x=1
x=1/2
This is the only answer I can get and someone told me it's wrong. Would someone please help me with this

Sara,
or maybe the answer is:
y=2xy
but that's kind of weird
