%0 Journal Article %T Undetermined coefficients for local fractional differential equations %A Khalil, Roshdi %A Horani, Mohammed Al %A Anderson, Douglas %J Journal of Mathematics and Computer Science %D 2016 %V 16 %N 2 %@ ISSN 2008-949X %F Khalil2016 %X We discuss the method of undetermined coefficients for fractional differential equations, where we use the (local) conformable fractional derivative presented in [R. Khalil, M. Al Horani, A. Yousef, M. Sababheh, J. Comput. Appl. Math., 264 (2014), 65--70]. The concept of fractional polynomials, fractional exponentials and fractional trigonometric functions is introduced. A method similar to the case of ordinary differential equations is established to find a particular solution for nonhomogenous linear fractional differential equations. Some other results are presented. %9 journal article %R 10.22436/jmcs.016.02.02 %U http://dx.doi.org/10.22436/jmcs.016.02.02 %P 140--146
