The resulting menu include some of the functions already introduced in the 
previous section, namely, ARG, ABS, CONJ, IM, NEG, RE, and SIGN.  It also 
includes function i which serves the same purpose as the keystroke combination 
„¥
, i.e., to enter the unit imaginary number i in an expression.  
The keyboard-base CMPLX menu is an alternative to the MTH-based CMPLX 
menu containing the basic complex number functions.  Try the examples shown 
earlier using the keyboard-based CMPLX menu for practice.
Functions applied to complex numbers
Many of the keyboard-based functions defined in Chapter 3 for real numbers, 
e.g., SQ, ,LN, e
x
, LOG, 10
X
, SIN, COS, TAN, ASIN, ACOS, ATAN, can be 
applied to complex numbers.  The result is another complex number, as 
illustrated in the following examples.  To apply this functions use the same 
procedure as presented for real numbers (see Chapter 3).
