Calculating inverse on a TI

  1. Mar 4, 2008 #1
    My quiz is in a couple of hours. And I can't figure out how to calculate the inverse of a square matrix on a Ti83. Does anyone know how?

    Just like you would find the multiplicative inverse of a number: use A ^ ( -1 ) where A is your matrix. Be sure to have parentheses around the -1.
