WebThe equation θ = π / 2 is the equation for this half-plane. From relationship (1), the ratio between x and y can be written, for example, as y / x = tan θ. If θ is held constant, then the ratio between x and y is constant. Thus, the equation θ = constant gives a line through the origin in the x y -plane.
