three dimensional vector. Elements of a vector are separated
with a comma, entered by pressing z. The elements stored
in a vector cannot be complex numbers or vectors themselves.
Vectors can also be used in equations and programs.
Vectors may be subtracted, multiplied, divided, and multiplied
by a constant. The º^ function computes the magnitude of
a vector.
To determine the dot product of and in ALG
mode, press:
{3zÕy{3zÏ.
In RPN mode, press:
{3zÏ{3zy. The dot
product is equal to 6.
