## anonymous one year ago The Cartesian coordinates of a point in the xy-plane are (x, y) = (-3.06, -2.24) m. Find the polar coordinates of this point. r = θ =

its obvious that $$\theta$$ should be between 180 and 270 degrees since both x and y coordinates are negative

BAdhi is right. $\theta$ should be in between 180 and 270 degrees. r is $\sqrt{?}$(xx+yy) . and then . $\theta$ =$\tan^{-1}$ y/x . :)

lol sorry im new here so dont know how to write those equations properly. r is the square root of (x^2 + y^2) and theeta is tan inverse (y/x)
