On a functional equation of trigonometric type
In this paper, we study the functional equation, f(x+y)f(x)f(y) = d sinx sin y. Some generalizations of the above functional equation are also considered.
متن کاملSome Trigonometric Identities Involving Fibonacci and Lucas Numbers
In this paper, using the number of spanning trees in some classes of graphs, we prove the identities: Fn = 2n−1 n √
متن کاملList of trigonometric identities
Cosines and sines around the unit circle In mathematics, trigonometric identities are equalities that involve trigonometric functions and are true for every single value of the occurring variables. Geometrically, these are identities involving certain functions of one or more angles. They are distinct from triangle identities, which are identities involving both angles and side lengths of a tri...
متن کاملHyers-Ulam stability of a generalized trigonometric-quadratic functional equation
The Hyers-Ulam stability of the generalized trigonometric-quadratic functional equation ( ) ( ) ( ) ( ) ( ) ( ) 2 F x y G x y H x K y L x M y + − − = + + over the domain of an abelian group and the range of the complex field is established based on the assumption of the unboundedness of the function K. Subject to certain natural conditions, explicit shapes of the functions H and K are determine...
متن کاملFibonacci numbers and trigonometric identities
Webb & Parberry proved in 1969 a startling trigonometric identity involving Fibonacci numbers. This identity has remained isolated up to now, despite the amount of work on related polynomials. We provide a wide generalization of this identity together with what we believe (and hope!) to be its proper understanding.
