Answer 14

this is when you have to use a scientific calculator i believe i remember learning about this in geometry

Answer 15

it looks like this

so get your integrations limits by solving r = 0 for \(\theta\)

so r is first zero at \(1 - 2 \sin \theta = 0\), and then it's -1 at \(\pi/2\) and then back to zero at \(5 \pi /5\)

but don't take my word, check it for yourself...

Answer 16

I don't know about the calculator method.. But I think you must indeed look at the graph and see for what range of \(\theta\) the inner loop is drawn.
