(a)
The matrix form of the following set of equations,
Answer to Problem 1P
Solution:
The matrix form of the set of equations is,
Explanation of Solution
Given:
The set of equations,
Consider the set of equations,
The set of equations can be written as,
These equations have three unknowns
The matrix form of the above set of equations can be written as,
Where, A is the coefficient matrix.
Therefore, the matrix form of the set of equations is,
(b)
To calculate: The matrix multiplication of the coefficient matrix with its transpose, that is
Answer to Problem 1P
Solution:
The matrix multiplication of the coefficient matrix with its transpose is,
Explanation of Solution
Given:
The coefficient matrix,
Formula used:
Transpose of the matrix
Calculation:
Consider the coefficient matrix,
The transpose of the matrix A is denoted by
Multiplication of the coefficient matrix and its transpose is,
Therefore, the matrix multiplication of the coefficient matrix with its transpose is,

- 11. Find two nonzero matrices and such that.arrow_forwardIn a previous section, we showed that matrix multiplication is not commutative, that is, ABBA in most cases. Can you explain why matrix multiplication is commutative for matrix inverses, that is, A1A=AA1 ?arrow_forwardIn Exercises 20-23, solve the given matrix equation for X. Simplify your answers as much as possible. (In the words of Albert Einstein, Everything should be made as simple as possible, but not simpler.) Assume that all matrices are invertible.
