“…Kim [15] has provided the hyperholomorphy and properties of functions of splitquaternionic variables which are expressed in hyperbolic coordinates, using Cullen's form. In addition to studying quaternion functions of the real variables, Kim [16] has examined the properties of functions for special quaternion variables such as dual quaternions and split quaternions.…”

Various attempts have been made in defining the derivative of a quaternionic function due to the noncommutativity of the product over quaternions. We observe that the difference in the left and right operations caused by the noncommutativity of the quaternion product is determined by the vector part of the quaternion. In this paper, we propose a corresponding derivative to replace the derivative of a quaternion-valued function of a quaternionic variable using the component terms of a quaternion. Further, the analogous constant, product, and quotient rules for the proposed calculations are given. Application of the proposed derivatives is provided to compute the derivatives of elementary functions. Several illustrations are also presented.
