Vectors on the TI-86
A vector is a one-dimensional array, arranged in either one row or one column. The vector
elements can be real or complex. You can create, display, and edit vectors on the home screen
or in the vector editor. When you create a vector, the elements are stored to the vector name.
The TI
-
86 vector editor displays a vector vertically. On the home screen, a vector is entered
and displayed horizontally. When you use a vector in an expression, the TI
-
86 automatically
interprets the vector in the form (row vector or column vector) that is appropriate for the
expression. For example, a column vector is appropriate for the expression
matrix
¹
vector
.
On the TI
-
86, you can store up to 255 elements to a vector in rectangular form. You can use
two- or three-element vectors to define magnitude and direction in a two- or three-
dimensional space. You can express two- or three-element vectors in different forms,
depending on the type of vector.
