Operations
With
Complex
Numbers
The HP-32S can use complex numbers in the form
x + iy.
It has operations for complex arithmetic
(+,
—,
x,
-;-),
complex
trigonometry (sin, cos, tan),
and
the mathematics functions —z,
1/z,
z-ft-,
In z,
and
e*
(where
z1
and
z2 are complex numbers).
Complex numbers in the
HP-32S
are
handled
by entering each
part
(imaginary and real) of a complex number as a separate entry. To en
ter two complex numbers, you enter four separate numbers. To do a
complex operation, press
1H"cmplx
I before the operator. For example,
to
do
(2 + i4) + (3 + f5),
press 41
enter
121
enter
151
enter
13Hl cmplx I\±\. The result is 5 +
i"9.
(Press |x$y| to see
the
imaginary part.)
