  8. Hyperbolic angle - Wikipedia

    en.wikipedia.org/wiki/Hyperbolic_angle

    The curve represents xy = 1. A hyperbolic angle has magnitude equal to the area of the corresponding hyperbolic sector, which is in standard position if a = 1. In geometry, hyperbolic angle is a real number determined by the area of the corresponding hyperbolic sector of xy = 1 in Quadrant I of the Cartesian plane.

  9. Tanh-sinh quadrature - Wikipedia

    en.wikipedia.org/wiki/Tanh-sinh_quadrature

    Tanh-sinh quadrature is a method for numerical integration introduced by Hidetoshi Takahashi and Masatake Mori in 1974. [1] It is especially applied where singularities or infinite derivatives exist at one or both endpoints.
