%0 Journal Article %T Geometric meaning of conformable derivative via fractional cords %A Khalil, Roshdi %A AL Horani, Mohammed %A Abu Hammad, Mamon %J Journal of Mathematics and Computer Science %D 2019 %V 19 %N 4 %@ ISSN 2008-949X %F Khalil2019 %X In this paper, we answer the question that many researchers did ask us about: "what is the geometrical meaning of the conformable derivative?". We answer the question using the concept of fractional cords. Fractional orthogonal trajectories are also introduced. Some examples illustrating the concepts of fractional cords and fractional orthogonal trajectories are given. %9 journal article %R 10.22436/jmcs.019.04.03 %U http://dx.doi.org/10.22436/jmcs.019.04.03 %P 241--245 %0 Journal Article %T On conformable fractional calculus %A T.
