TY - JOUR T1 - METHOD OF VARIATION OF PARAMETERS FOR THE THIRD-ORDER LINEAR PROPORTIONAL DYNAMIC EQUATIONS AU - Gülşen, Tuba AU - Acar, Mehmet PY - 2023 DA - December DO - 10.55930/jonas.1321901 JF - Bartın University International Journal of Natural and Applied Sciences JO - JONAS PB - Bartın Üniversitesi WT - DergiPark SN - 2667-5048 SP - 135 EP - 144 VL - 6 IS - 2 LA - en AB - The differentiation and integration of an integer order are known as fractional calculus. It is possible to think of the proportional derivative as a generalization of a congruent fractional derivative, which is one of the types of fractional calculus. In this article, utilizing the proportional derivative and its characteristics on the time scale, the method of variation of parameters for the third-order linear nonhomogeneous differential equations is given. Then, an example is provided to illustrate how to apply the provided approach. KW - Time scales KW - variation of parameters KW - proportional derivative CR - 1. Abdeljewad, T. (2015).
