Calculating the series expansion of a hyperbolic cosine 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 as follows. The previous expression is not zero for and the corresponding sum has the following value. Mathematica can evaluate derivatives of the hyperbolic cosine function of an arbitrary positive integer order. Mathematica can calculate finite symbolic sums that contain the hyperbolic cosine function. Here are some examples. Mathematica can calculate infinite sums including the hyperbolic cosine function. Here are some examples. Mathematica can calculate some finite symbolic products that contain the hyperbolic cosine function. Here is an example. Mathematica can calculate a huge set of doable indefinite integrals that contain the hyperbolic cosine function. Here are some examples. Mathematica can calculate wide classes of definite integrals that contain the hyperbolic cosine function. Here are some examples. Mathematica can calculate limits that contain the hyperbolic cosine function. Here are some examples. The next inputs solve two equations that contain the hyperbolic cosine function. Because of the multivalued nature of the inverse hyperbolic cosine 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. Here are differential equations whose linear independent solutions include the hyperbolic cosine function. The solutions of the simplest second‐order linear ordinary differential equation with constant coefficients can be represented using and . Mathematica supports the main integral transforms like direct and inverse Laplace and Fourier transforms that can give results that contain classical or generalized functions. Mathematica has built‐in functions for 2D and 3D graphics. Here are some examples.
