    This more general formula is known as Bretschneider's formula. It is a property of cyclic quadrilaterals (and ultimately of inscribed angles ) that opposite angles of a quadrilateral sum to 180°. Consequently, in the case of an inscribed quadrilateral, θ is 90°, whence the term

  8. Arithmetico-geometric sequence - Wikipedia

    In general, these series with =, =, =, and = give the expectations of "the number of trials until first success" in Bernoulli processes with "success probability" . The probabilities of each outcome follow a geometric distribution and provide the geometric sequence factors in the terms of the series, while the number of trials per outcome ...
