COMPLEX NUMBER CALCULATIONS

To carry out addition, subtraction, multiplication, and
division using complex numbers, press b 3 to
select CPLX mode.
Results of complex number calculations are expressed
using two systems:
① @ E : Rectangular coordinate system
② @ u : Polar coordinate system

Complex Number Entry

① Rectangular coordinates
x-coordinate + y-coordinate O
or x-coordinate + (-) O y-coordinate
② Polar coordinates
r Q θ
r : absolute value
• On selecting another mode, the imaginary part of any
complex number stored in the independent memory
(M) and the last answer memory (ANS) will be
cleared.
• A complex number expressed in rectangular
coordinates with the y-value equal to zero, or
expressed in polar coordinates with the angle equal
to zero, is treated as a real number.
• Press N 1 to return the complex conjugate of
the specifi ed complex number.
