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.
Not too easy. Not too difficult.
Course Overview:
Prof Williams is great at explaining the intricacies of linear algebra.
Course highlights:
In this course, you learn many of the core concepts of linear algebra, including determinants, vector spaces, and eigenvalues.
Hours per week:
6-8 hours
Advice for students:
Attend class, do the homework on time, and review notes often.
Not too easy. Not too difficult.
Course Overview:
at the time, the material seemed very hard but after finishing the class and still using the concepts, they seem easier and are obviously very useful
Course highlights:
lectures were not very useful to go to but clas was very helpful and webwork helped to master concepts
Hours per week:
6-8 hours
Advice for students:
there is longf homework so be prepared to put time into it. not too many problems but the problems are very long and time consuming. no practice midterm or final
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.
