Question

Given the rectangular equation xy=1, how do I write an equivalent polar equation?

Answer 1

substitute:
x=rcos(theta)
y=rsin(theta)

Answer 2

is that all I'm supposed to do? That isn't one of the answer choices

Answer 3

you might have to do some algebra to get the answer choices...

Answer 4

I guess this is lost on me I cannot figure out where to go.

Answer 5

\[r^2\sin \theta \cos \theta=1\]\[\frac{r^2}{2}\sin (2\theta)=1\]
