12.2 Introduction to VECTORS

• vector a quantity having magnitude and
  direction
• bound vector arrow from one point to another
• free vector a class of all bound vectors with
  a given length and direction

A bound vector in 2 dimensions is described by
two triples (a1, a2, a3) and (b1, b2, b3). A free
vector is described by one triple ? c1, c2, c3 ?
A bound vector is fixed, but a free vector is
movable.
24
EQUIVALENT BOUND VECTORS
HAVE THE SAME LENGTH AND DIRECTION
25
EQUIVALENT BOUND VECTORS
GENERATE A PARALLOGRAM
26
ADDING TWO FREE VECTORS
NOTICE THE COMMUTATIVITY OF VECTOR ADDITION
27
SUBTRACTING TWO FREE VECTORS
28
MULTIPLY VECTOR BY A POSITIVE REAL NUMBER (SCALAR)
If cgt0, then ca has the same direction as a,
but the length (magnitude) of ca is c times
the length of a.
29
MULTIPLY VECTOR BY A NEGATIVE REAL NUMBER (SCALAR)
If clt0, then ca has a direction opposite to
a, but the length (magnitude) of ca is c
times the length of a.

12.2 0 The bound vector for 2 points
The bound vector from A(2, -3, 4) to B(-2, 1,
1) is the directed line segment AB. A

31
12.2 1 The free vector for 2 points
The bound vector from A(2, -3, 4) to B(-2, 1,
1) is the directed line segment AB. A The
corresponding free vector is B
? (-2)-(2), (1)-(-3), (1)-(4) ? ? -4, 4, -3 ?
32
12.2 Magnitude or Length of a Vector
33
12.2 Multiplying a Vector by a Scalar
Vectors which are parallel or antiparallel
differ only by a scalar multiplier.
