Entering complex numbers
Complex numbers in the calculator can be entered in either of the two
Cartesian representations, namely, x+iy, or (x,y). The results in the calculator
will be shown in the ordered-pair format, i.e., (x,y). For example, with the
calculator in ALG mode, the complex number (3.5,-1.2), is entered as:
„Ü3.5‚í\1.2`
A complex number can also be entered in the form x+iy. For example, in
ALG mode, 3.5-1.2i is entered as:
3.5 -1.2*„¥`
The following screen results after entering these complex numbers:
In RPN mode, these numbers will be entered using the following keystrokes:
„Ü3.5‚í1.2\`
(Notice that the change-sign keystroke is entered after the number 1.2 has
been entered, in the opposite order as the ALG mode exercise), and
³3.5 -1.2*‚¥`
(Notice the need to enter an apostrophe before typing the number 3.5-1.2i in
RPN mode). The resulting RPN screen will be:
Notice that the last entry shows a complex number in the form x+iy. This is so
because the number was entered between apostrophes, which represents an
algebraic expression. To evaluate this number use the EVAL key( µ).
Once the algebraic expression is evaluated, you recover the complex number
(3.5,1.2).
