The Differential Equation in Terms of Jacobsthal and Jacobsthal – Lucas Numbers
Main Article Content
Abstract
In this paper, we study Jacobsthal sine, Jacobsthal-Lucas sine, Jacobsthal cosine, Jacobsthal-Lucas cosine, Jacobsthal tangent, Jacobsthal-Lucas tangent, Jacobsthal cotangent, Jacobsthal-Lucas cotangent, Jacobsthal secant, Jacobsthal-Lucas secant, Jacobsthal cosecant, and Jacobsthal -Lucas cosecant. Furthermore, we establish some identities of Jacobsthal sine, Jacobsthal-Lucas sine, Jacobsthal cosine, Jacobsthal-Lucas cosine, Jacobsthal tangent, Jacobsthal-Lucas tangent, Jacobsthal cotangent, Jacobsthal-Lucas cotangent, Jacobsthal secant, Jacobsthal-Lucas secant, Jacobsthal cosecant, and Jacobsthal -Lucas cosecant.
