# Cayley Hamilton procedure on the TI89 step by step

The Cayley Hamilton is a nifty procedure to find the inverse of a matrix using the characteristic polynomial of a given square matrix. So no Row Echolon or similar is needed. We just included this Cayley Hamilton in the Linear Algebra Made Easy TI89. Best of all complete steps are shown until the inverse matrix… (read more)

# Linear Algebra Made Easy UPDATE: Solve a system of equations in matrix format with parameter solution

We just updated Linear Algebra Made Easy : It can now step-by-step Solve a system of equations given in matrix format with parameter solution. A wonderful description of the 3 different types of solutions ( (in)dependent or inconsistent ) can be found at https://people.richland.edu/james/lecture/m116/matrices/matrices.html Only dependent solutions yield parameter solutions. Linear Algebra Made Easy will… (read more)
