PRODUCT DESCRIPTION

Included in this zip folder are 5 PDF files. 2 are for instruction, 2 are assignments and 1 is a printable study guide. A brief description of each:

Intro #1 is a 25 page file. The determinant is figured by the matrix of cofactors. The student is introduced to:
1. Minor values
2. The matrix of minors
3. the matrix of signs
4. The matrix of cofactors
5. The determinate of a 3x3 matrix
6. Cramer's Rule

Intro #2 is an 18 page file. The determinant is figured by repeating columns and multiplying diagonals.

The student printable is a 1 page file. There is information about:
1. The matrix of minors
2. The matrix of signs
3. The matrix of cofactors
4. The determinant
5. The adjugate matrix (for later discussion)
6. The 3x3 inverse matrix (for later discussion)

Assignment #1 is a 15 question short answer and multiple choice file. It is for Intro #1 where the matrices of minors and cofactors are discussed. Identifying Cramer's Rule is also in this assignment. It is on 1 page for easy printing.

Assignment #2 is a 15 question short answer and multiple choice assignment. This assignment is from Intro #2. Only the diagonal method of finding the determinant is needed. Cramer's rule is used with these determinants. It is on 1 page for easy printing.
