Hello guys!

I'm trying to brush up on my calc. 2.

So I had two questions, find the points of intersections of both;

33) r = 2sin(theta)

r = 2sin(2theta)

I get to sin(theta)/sin(2theta)=1

what do I do with the "sin(2theta)."(Can this 2 be moved out?)

Answer: (0,0), (3^1/2, pi/3), (-(3^1/2), pi/3)

37) r=1

r^2 = 2sin(2theta)

Don't know what to do here...

1 = +/- 2sin(2theta)

...?

Answer: (1, pi/12), (1, 5pi/12), (1, 13pi/12), (1, 17pi/12)
