Homework Help: Pre-Calculus

Posted by Sara on Monday, December 13, 2010 at 7:57am.

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
