Vectors
A real number is a point on the real line R
To describe a point on a plane R2, we use two numbers, e.g., (3,-1)
In fact, this is just an expression of a point using rectangular
coordinate system

If we put the coordinates as , we have a vecto
Inner Product
For two vectors u, v in Rn, the inner product is defined as
v1
v
uT v = [u1 u2 . un ] 2 = u1v1 + u2 v2 + . + un vn
#

It is obvious that uTv= vTu
From inner product, we can define other attributes of a vector

Q1. Let 3 = 1 and 6= 1.
Find the value of 2011 + 1997 + 1.
Answer. Since 3 = 1 we have
2011 + 1997 + 1
= 3670+1 + 3665+2 + 1
= + 2 + 1 .
Now we also have
0 = 3 1 = ( 1)( 2 + + 1) .
Since 6= 1, 2 + + 1 = 0. So
2011 + 1997 + 1 = 0 .

Eigenvalues and Eigenvectors
For an nn matirx A, if there is a nonzero vector x such that Ax=x
for some scalar , then is an eigenvalue of A, and x is the
eigenvector corresponding to
If we view A as a mapping, Ax=x means that the mapping A acting

Matrices
As seen in the previous chapter, a matrix consists of vectors as
columns: A=[a1 a2 an]
For an mn matrix, its structure is
Two matrices are equal iff they have the same size and their
corresponding entries are equal
Sum of two matrices is just
