You enter a vector by specifying its components between square brackets;

1. Press 0 O

2. Enter the first component.

If you are entering a real vector rather than a symbolic vector,

immediately follow each component with a decimal point (as in the

example below).

3. Enter each subsequent component.

Separate rectangular components with a

comma but precede an angular

component with the angle sign: d. (The

angle sign can be entered by pressing

®HA)©6.)

Press

(ENTER).

You can also enter a vector by creating a single-row matrix with Matrix

Writer. This is explained later in this chapter.

_____

If the coordinates notation does not match

your entry, the HP 49G converts your entry

to tliat notation. In the example at the right,

the second argument—4.—is converted to

an angle measurement because the

coordinates notation is set to polar

(indicated by the polar annunciator). Note that symbolic vectors—

including those with integer elements—are not converted to the angle

measurements.

Vector mathematics

Two vectors can be added and subtracted on the HP 49G just as real

numbers are added and subtracted. For instance, to add two vectors,

You can also multiply and divide a vector by a scalar.

The HP 49G also provides a number of special commands for working

with vectors. Three of these commands—absolute magnitude, dot

product, and cross product—are described in detail in the next three

sections.
