Question

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 =

Answer 1

i got r = 3.79 and θ = 144, but my practice is keep saying my θ is wrong. So can anyone helps me to find the problem for me? thanks

Answer 2

my r value is
\[\sqrt{(3.06)^2+(2.24)^2}=3.79\]

so we both agree of that
