How do I work with a matrix like this?

  1. Mar 11, 2009 #1
    How do I work with a matrix like this??

    1. The problem statement, all variables and given/known data

    How do I go about solving a matrix like this:

    [ 3e^4t -2e^3t ]
    [ 4e^4t -5e^3t ]

    Like how would I get the determinant and stuff? Do I avoid the exponent looking things, or get rid of them somehow??

    Please help!

    2. Relevant equations



    3. The attempt at a solution

    Your matrix doesn't appear to be part of an equation, so there's nothing to solve. You can take the determinant of your matrix the same way you would any 2 x 2 matrix. You know how to multiply e^(at) by e^(bt), right?

    Actually...no..

    is it exponential multiplication?

    Do you know how to multiply 2^3 by 2^4?
