High Quality Content by WIKIPEDIA articles! A hyperbolic angle in standard position is the angle at between the ray to and the ray to where x > 1. The magnitude of the hyperbolic angle is the area of the corresponding hyperbolic sector which is loge x. Note that unlike circular angle, hyperbolic angle is unbounded, as is the function loge x, a fact related to the unbounded nature of the harmonic series. The hyperbolic angle is considered to be negative when 0 < x < 1.
