NOTE
Row Vector is a matrix with only 1 row�: A = [5 4 3] 1 X 3 matrix
Column Vector is a matrix with only 1 column�: A = EMBED Equation.3 3 X 1 matrix
Transposing Matrices
A = EMBED Equation.3 2 X 3 matrix
Then
AT = EMBED Equation.3 3X2 matrix
the transpose of a matrix replaces rows by columns. b) Matrix Laboratory 2: -bY + C = a
Now write this in matrix notation: EMBED Equation.3
EMBED Equation.3
or A.X = B
We can solve for the endogenous variables X, by calculating the inverse of the A matrix and multiplying by B:
Since AX=B ( X=A-1B
To invert the 2 X 2 A matrix, recall the steps from earlier in the lecture
If A = EMBED Equation.3 , then A �1 = EMBED Equation.3
In this case, where EMBED Equation.3
the determinant of A is :
|A| = 1.1 � [� 1.� b] = 1 � b
Cofactor Matrix: EMBED Equation.3
Transpose Cofactor Matrix: EMBED Equation.3
The inverse is�:
EMBED Equation.3
EMBED Equation.3 so X=A-1B
where EMBED Equation.3 and EMBED Equation.3
EMBED Equation.3
Thus, multiplying A-1B gives,
EMBED Equation.3
These are the solutions for the endogenous variables, C and Y, just as we derived using method 1.

Algebra 2 Matrices Review Multiple Choice Identify the choice that best completes the statement or answers the question. a) Product development b) Market penetration The matrix notation will allow the proof of two very helpful facts: * E b = β . e) none of the above Method 3: Using Cramers Rule
In the example above, where
EMBED Equation.3
EMBED Equation.3
EMBED Equation.3
Replace column 1 of A with the elements of vector B
EMBED Equation.3
Calculate the determinant of this as:|A1| = (I + G )(1) � ( �1)( a) = I + G + a
We saw earlier that the determinant of A is
| A | = 1� b
Therefore the solution using Cramers rule is:
EMBED Equation.3
Replace column 2 of A with the elements of vector b
EMBED Equation.3
Calculate the determinant of this as:|A2|=(1)(a) � (I+G)(� b) = a+b(I+G)
We saw earlier that the determinant of A is
| A | = 1� b
Therefore the solution using Cramers rule is:
EMBED Equation.3
(just as we derived using the other 2 methods)
