Ch. 6 Homework Questions 5,6,7
|
| |
I just want to check some solutions and ask a question.
For number five, I want to disprove the statement.
For (a,b) in R^2,
...+ |b|^2 = (|a| + |b|)^2 .
Since (|a| + |b|)^2 = |a|^2 + |b|^2 + 2|a||b| does not equal |a|^2 + |
b|^2 unless |a||b| = 0, then there is no inner product on R^2 such
that the associated norm is given by ||(a,b)|| = |a| + |b|.... more »

A Few Questions on Chapter 6
|
| |
On page 99, it says that "we want to think of ||z||^2 as the inner
product of z with itself," but his formula for it looks like the inner
product of z with the conjugate of z. I wanted to know what I am not
seeing.
On page 104, I am having trouble understanding the proof of the Cauchy-
Schwarz Inequality where Axler looks at what ||u||^2 is equal to based... more »

Former students,
I'll be teaching Math 110 this coming semester (Fall, 2008). If
you're getting this message, you might want to sign off from the Math
110 google group. Indeed, I might start using this group again for
online discussion and you might find that you're getting mail that
doesn't really interest you...... more »

John, I'm probably the zillionith customer, but could
you please email me as many of the following that are
not inconvenient to calculate:
1.) my grade on the final
2.) final grade in class
3.) mean on the final
Thank you very much, have a great summer! - Jason

random pre final questions
|
| |
We didn't end up covering Jordan Canonical form right?
Or did I miss that?
Secondly, did we ever prove in class the existence of
the adjoint in the case where T: V ---> W ?? (exercise sec 6.3 15)
The book leaves this as an exercise and I was having
trouble with this proof... - Jason

Review session in 51 Hildebrand, 6-8pm
|

Hi everyone,
for some reason I suspect my email didn't get sent out by the Google
group, even though it's been on the web interface since last night. So
just in case; I'll be in 51 Hildebrand, answering questions, etc, from
6-8pm -- that is, in half an hour!
