ok wait i think d is the name of the matrix....not determinant
ok i was looking over my notes and a little confused at what my prof was doing on his ti 89 in lecture last week.
the command line reads as follows...
rref(d-2 identity(3))
i forgot to reference this with the problem..
im thinking the d means determinant and 2 is an eignevalue and 3 is the identity of a 3 x 3 matrix?
is this right or am i wrong?
