How do you make that a matrix in the form of
[1 0 A]
[0 1 B]
?
I have a system, but i missed the lessons on all that matrix stuff. If you could tell me how to make one too, that'd be great.(you were the first person with that i found with a solved system so yeah)
To create a matrix in the form you mentioned:
[1 0 A]
[0 1 B]
You can use what is known as an identity matrix, with the values A and B inserted. An identity matrix is a special square matrix with ones on the main diagonal and zeros elsewhere.
Here's how you can do it step by step:
1. Write down the first row: [1 0 A]
This row represents the coefficients of the variables in your system. In this case, the first variable has a coefficient of 1, the second variable has a coefficient of 0, and the last column represents a constant, which is A.
2. Write down the second row: [0 1 B]
This row represents the coefficients of the variables in your system again, but with the second row indicating the second equation or condition. In this case, the first variable has a coefficient of 0, the second variable has a coefficient of 1, and the last column represents a constant, which is B.
That's it! Now you have a matrix in the desired form. Just replace A and B with your desired values.
Remember, matrices can represent systems of equations, where the columns correspond to variables and the rows correspond to equations/conditions. The combination of the numbers in the matrix represents the coefficients of the variables and constants.
