bc: Calculate a sine/cosine/arctangent/natural logarithm/exponential function using `mathlib`.

$ bc --mathlib --expression='${select}(${1})'

try on your machine

The bc command is a command-line calculator tool that allows you to perform mathematical calculations in the terminal.

The command bc --mathlib --expression='${select}(${1})' is using the bc command with the following options and arguments:

--mathlib option: This option tells bc to load the math library, which provides additional mathematical functions and constants.
--expression='${select}(${1})' option: This option specifies the expression to be evaluated by bc. The ${select} part is a placeholder that represents the selected value from the input, which will be replaced when the command is executed. The ${1} is also a placeholder representing the first argument passed to the command.

In summary, this command runs bc with the math library loaded and evaluates the expression given by the selected value (using ${select}) and the first argument ${1} passed to the command. The exact result will depend on the value of ${select} and ${1}.
