Unformatted text preview: r as a function of θ (similar to how, in Cartesian coordinates ( x , y ), functions are usually expressed as y as a function of x ). For example, if a function in polar coordinates is written as r = 2 θ , then r would have the same units as θ . But r should be a unitless quantity, hence using radians for θ makes more sense in this case....
