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 41enter 121 enter 151 enter 13Hl cmplx I\±\. The result is 5 + i"9.
(Press |x$y| to see the imaginary part.)
