Operations under special Mathematica functions Series expansions Calculating the series expansion of a hyperbolic cosecant function to hundreds of terms can be done in seconds. Mathematica comes with the add‐on package DiscreteMath`RSolve` that allows finding the general terms of the series for many functions. After loading this package, and using the package function SeriesTerm, the following term of can be evaluated. This result can be verified by the following process. Differentiation Mathematica can evaluate derivatives of the hyperbolic cosecant function of an arbitrary positive integer order. Indefinite integration Mathematica can calculate a huge set of doable indefinite integrals that contain the hyperbolic cosecant function. The results can contain special functions. Here are some examples. Definite integration Mathematica can calculate wide classes of definite integrals that contain the hyperbolic cosecant function. Here are some examples. Limit operation Mathematica can calculate limits that contain the hyperbolic cosecant function. Here are some examples. Solving equations The next inputs solve two equations that contain the hyperbolic cosecant function. Because of the multivalued nature of the inverse hyperbolic cosecant function, a message is printed indicating that only some of the possible solutions are returned. A complete solution of the previous equation can be obtained using the function Reduce. Solving differential equations Here is a linear firstorder differential equation that is obeyed by the hyperbolic cosecant function. Here is a nonlinear secondorder differential equation that is obeyed by the hyperbolic cosecant function. Mathematica solves the differential equation as a rational function of . But it is straightforward to express the result as a hyperbolic cosecant function. Plotting Mathematica has built‐in functions for 2D and 3D graphics. Here are some examples.
