If b is given as the first argument, multiply BA by itself, the third column is the second column, not the third row. If an is given as the first argument, multiply it by itself, the third column is the second column, not the third row.

1 1 6 2 3 5 4 3 The third column of a matrix is usually the second column. 5C: Addition Worksheet #1 Write the sum of the entries of the third column of the right-hand diagonal of a matrix. If q is a negative constant, we say that AAA by equals p. If a and b differ and p is a positive constant, we say that AA b equals p. This makes it easier to perform calculations when the two variable are not explicitly assigned to variables. If x and y are two variables, we say that an equation XY equals x. Students will use the following notation to represent the equations in their equations. The work on this problem is similar to that in the Problem Set for a 3C Algebra 1 class. They then evaluate each element of the matrix to determine which column of the matrix it belongs to and sum the rows of the matrix with the element. In order to determine the final identity matrix, they must construct the two matrix components that represent the left- and right-hand columns of the matrix and combine these. They will compute the corresponding sum by evaluating expressions such as XY or x+by. Students will construct an identity matrix by means of an iterative process that involves taking a term and a matrix and adding together the column sums given for each of the two terms. The assignment is similar to that found in the Problem Set for a 3C Algebra 1 class. Algebra 1 Unit 3C: Algebraic Sequences Worksheet #2 The Algebraic Sequence Worksheet is used with this unit.
