4. Elementary Functions

Choose a function

\cosh x

denotes the hyperbolic cosine function; see DLMF (4.28.2).
Computations are currently restricted to real values of

x

, with

| x | \leq 10^{9}

Evaluate

\cosh x

as a Tabulation or Comparison?

Get function arguments from form or data file?

Specify the data file to compare tofor arguments:
Note: The lines in the data file must contain values for

x

and

\cosh x

in that order, separated by commas or spaces.

Specify grid for function parameters and arguments:

Choose

x

starting from ending with stepping by
