a = [1] Simple as that!!
did you mean an identity matrix (I)?
then a would equal:
a= [ 1 0 0
0 1 0
0 0 1 ]

Use the following matrix x equals 1 2 3 4 4 -1 -2 0 6 1 5 -3 what is a23 equal a -2 b 1 c -1 d 5?
Let me know what the size of the matrix is and put brackets around the rows so I can understand the question. I can help with linear algebra
How do you find a negative matrix in algebra?
For example, if you have [ -4 1 0 3] as your matrix, it would be negative 4. Whatever negative number is in your matrix is your answer.
What are the Idiosyncrasies of matrix algebra?
idiosyncrasies of matrix are the differences between matrix algebra and scalar one. i'll give a few examples. 1- in algebra AB=BA which sometimes doesn't hold in calculation of matrix. 2- if AB=0, scalar algebra says, either A, B or both A and B are equal to zero. this also doesn't hold in matrix algebra sometimes. 3- CD=CE taking that c isn't equal to 0, then D and # must be equal in scalar algebra. Matrix again tend to deviate from this identity. its to be noted that these deviations from scalar algebra arise due to calculations involving singular matrices.
Is Inverse of the inverse matrix the original matrix?
Let A by an nxn non-singular matrix, then A-1 is the inverse of A. Now (A-1 )-1 =A So the answer is yes.
How is elementary algebra different from algebra 1 or 2?
It isn't; the algebra 1 and 2 that you get taught in middle or high school is elementary algebra. When (if you want to) you get into more advanced algebra, you can learn linear algebra (matrix algebra) and abstract algebra (which involves sets, operations on sets, groups, and many more concepts), and probably several more types of algebra I've never heard of.
What is 8n equals 1 algebra question?
8n = 1 n = 1/8
What does 1 equals 6 X equal in Algebra?
1=6x x=1/6
When simplifying algebra can you simplify 1 over a equals 1 over b to a equals b?
1/a = 1/b: cross multiplying gives a = b
If properties of matrix addition let A B C D the m n matrix then 1 A plus B B plus A?
Yes. Matrix addition is commutative.
What is B called in the matrix representation of a system of linear equations when written as AX equals B?
A = coefficient matrix (n x n) B = constant matrix (n x 1)
Algebra solution for x-2y equals -6 x-2y equals 2?
I think there's a typo, otherwise -3 = 1
Is an invertible idempotent matrix the identity matrix?
The assertion is true. Let A be an idempotent matrix. Then we have A.A=A. Since A is invertible, multiplying A-1 to both sides of the equality, we get A = I. Q. E. D
