Math 262
Problem set 3, due Wednesday, February 4
Do the following problems from the book:
Also, try to make some progress on the following, but don't hand
it in: what can you find out about inverses of upper triangular
matrices? (An n × n matrix A is upper
triangular if every entry Aij is zero when i > j.
In other words, it has all zeros below the main diagonal.) For
example, can you find nice formulas in the 2 × 2 case, or the 3
× 3 case? What if all of the entries on the diagonal are 1? We
will discuss your ideas in class on Wednesday, or maybe Friday.
