175 is a less intensive version of multivariable calculus.
The intensive development of fractional calculus and its widespread applications in several disciplines clearly indicate the interest of researchers and modelers in the subject.
Recently, because of the intensive development of fractional calculus theory and its applications, the initial and boundary value problems (BVPs for short) of fractional differential equations have gained popularity (see [5 15] and the references therein).
As a result of the intensive development of fractional calculus, fractional differential equations have been proved to be useful tools in modeling of phenomena in various fields of science and economics and have been greatly developed (see [1 5] and the references therein).
In recent years, because of the intensive development of the fractional calculus theory itself and its applications, fractional differential equations have been of great interest.
Many faculty members were not in favor of the change, either because the change was perceived as being too difficult for the students or, for the research intensive-faculty, that a background in calculus was unimportant to their own research.
This is due to the intensive development of the theory of fractional calculus itself as well as its applications.
It is caused by the both intensive development of the theory of fractional calculus itself and applications, see [1 6].
Fractional differential equations have given rise to abroad attention of many researchers by the intensive development of the theory of fractional calculus itself.
