Abstract

Beginning with the fractional exponential, which is frequently used in applications, fractional Taylor expansions of several elementary functions in both the ordinary and Laguerrian cases are introduced, showing that some basic formulas continue to apply to new expansions. Some graphs obtained using the computer algebra system Mathematica© are given for illustration purposes.
