Division, analytic function.Matrix shortcut: Since a/b is mathematically identical to (1/b)*a, HP allows the use of as a shortcut for matrix multiplication by an inverse. If you have two matrices on the stack (or an array and a matrix), you can just press (instead of 1/X SWAP * ) to do such things as solve systems of linear equations.

Example: Solve this system of linear equations:

Method:

This means thatx=5 andy=9. This works for any number of variables; just divide the constants by the coefficients to find the solutions.
