STUDY GUIDE - LESSON 27
A
review of last week's homework is
an appropriate place to begin today's
lesson.
Homework


You
will now continue Vectors by reviewing
LENGHT OF A VECTOR LENGTH OF VECTORS
ON CARTESIAN DIAGRAM

While
the aspects of vectors presented above
are relatively simple the points noted
are sometimes missed by students to
their detriment. Please note them
well.

SOLUTION
(i)
From the diagram, the coordinates
of A = (6,8) and B = (5, 11)
It was illustrated in last week's
lesson that if the coordinates of
A is (6, 8), then the
I
do hope that you realize that the
coordinates of the point P is (8,
15).
(ii)
Using the formula for length:

I
do hope that you had no difficulty
in understanding the above. If this
is the case, please attempt the following
for homework.
