This quantity raised to the n is equal to this quantity raised to the n - 1 plus this quantity raised to the n - 2, which is a recurrence relation useful in deriving the Binet formula.
This quantity raised to the n is equal to this quantity raised to the n - 1 plus this quantity raised to the n - 2, which is a recurrence relation useful in deriving the Binet formula. This quantity's expression as a continued fraction involves only ones. One plus the reciprocal of this value is equal to this value. One way to calculate this quantity is to take the diagonal of a pentagon to its side. It is defined such that its square is equal to it plus 1. For 10 points, name this number commonly symbolized phi, equal to 1 plus the square root of 5 all over 2 or approximately 1.618.
