WebFeb 25, 2016 · Explanation: In rectangular form θ = tan−1( y x). Hence tan−1( y x) = π 3 or. ( y x) = tan( π 3) = √3 or y = √3x. Hence θ = π 3 is written as y = √3x in rectangular form. WebMar 18, 2014 · 1 Answer. θ = k would be a line passing through the origin, with slope tan ( k). So here, the slope would be tan ( π), but only in the backward direction, that is the the negative x axis in this case. Here is a picture, showing two graphs.
