Question

How do you find the polar equation for `x^2+y^2=7`?

Answer 1

`r^2=7`

Explanation:

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

`color(orange)"Reminder " color(red)(|bar(ul(color(white)(a/a)color(black)(r=sqrt(x^2+y^2))color(white)(a/a)|)))`

`rArrr^2=x^2+y^2`

`rArrx^2+y^2=7rArrr^2=7" is the polar equation"`
