Matrix Representation of Linear Equations:
This brings up a new page, which lets you do a Matrix Inverse
and other operations on a matrix on the LHS.
You can tinker with the matrices and watch their products change.
Matrix Multiplication With Examples:
This brings up a different page, which lets you build an Inverse Matrix
for a system of equations in Xi.You can tinker with the matrices and watch their products change.
Matrix Multiplication With Examples:
You can tinker with the constants for X and watch the answers change.
Solving Systems of Linear Equations:
This loads the matrix example in a system of equations (RHS).
You can swap sides and see the product change.
This loads a matrix that has no inverse.
You can tinker with the constants to change that.
=> Cheat Sheet This loads the same matrix as '2 by 3' on LHS.
You can solve it after clicking here.
' This loads the matrix (LHS) that has no solution.
Again, you can change constants to fix that.
This loads another matrix with no solution.
Due to roundoff errors, it lets you divide by zero to get an invalid inverse.
