    Term:

    Invertible

    Definition:

    -when AC = I or BA = I. -Let A be an nxn matrix then A is invertible if there is another nxn matrix A^-1 such that AA^-1 = Identity and A^-1A = Identity -A has a pivot in every row and column -reduced echelon form of A is Identity -linear dependence = not invertible.

    | No strong feelings either way.

    | No strong feelings either way.

    Not too easy. Not too difficult.

    Course Overview:

    I felt indifferent about this class because it was one that I had to take for my major. It wasn't too difficult, but my professor especially was very hard to understand. I recommend going to office hours or enrolling in CLAS.

    Course highlights:

    This course was titled Linear Algebra, so it was a lot of simple computations, functions, and matrices.

    Hours per week:

    3-5 hours

    Advice for students:

    You do have to work hard for this class, but you shouldn't stress about it too much. If you pay attention to lecture or receive outside help, you will succeed.
