Notes
• These functions can be used in the CMPLX Mode, as long as a complex number is not
used in the argument. A calculation like
i
× sin(30) is supported for example, but sin(1 +
i
)
is not.
• The angle unit you need to use in a calculation is the one that is currently selected as the
default angle unit.
