Q1: clarification on the meaning of polynomial transform of order Q

Just making sure:
A non linear transform that is polynomial of order Q looks like this:
Q=1
Q=2
Q=3

Re: Q1: clarification on the meaning of polynomial transform of order Q

Maybe this is the same question?

Is the answer to question 1 supposed to be exact or approximate?

Thank you for your help!

Correct.

Remember that the problem states that the constant (zeroth) coordinate in not counted in the dimensionality.

So many "nearest" answers that we forget after a while what "exact" means.

Exactly. :)

I really want to be careful. Because I've seen in the past exercises, that a small bug in the program or a little misinterpretation takes you in a different direction. :)

Yes, I know. I deliberately left it in, for completion reasons, and maybe to see if I get a comment like this :)
I am afraid I might have missed something and have the wrong answer. Although I am not trying to train on the comments :D
