Creating a Complex Vector
If any element of a vector is complex, all elements of the vector are displayed as complex.
For example, when you enter the vector
ã
1,2,(3,1)
ä
, the TI
-
86 displays
ã
(1,0) (2,0) (3,1)
ä
.
To create a complex vector from two real vectors, the syntax is:
realVector
+(0,1)
imaginaryVector
¶
complexVectorName
realVector
contains the real part of each element and
imaginaryVector
contains the
imaginary part.
Displaying a Vector
To display a vector, paste the vector name to the home screen, and then press
b
.
To display a specific element of
vectorName
on the home screen or in a program, the syntax is:
vectorName
(
element#
)
Real two- and three-element vector results are displayed according to the current vector
mode setting:
RectV
,
CylV
, or
SphereV
(Chapter 1). You can select a vector conversion
instruction from the
VECTR OPS
menu to override the mode setting (page 173).
Complex vectors are displayed in rectangular form only.
