Question

How do you convert the rectangular equation `y=9` into polar form?

Answer 1

`r=9/sintheta`

Explanation:

To convert from `color(blue)"rectangular to polar form"`

`color(orange)"Reminder " color(red)(bar(ul(|color(white)(2/2)color(black)(x=rcostheta, y=rsintheta)color(white)(2/2)|)))`

`y=9`

`rArrrsintheta=9`

`rArrr=9/sinthetalarr" in polar form"`
