Hi there,

Please find my questions in the attached file, in red and green.

Thanks

I have moved this thread to a more appropriate forum.

 

If you examine the indices of the coefficients of (1) you should be able to answer your first red question fairly readily.

Here's a better idea for your first green question -- why don't YOU answer it as best you can and we'll look it over and provide feedback on whether you are correct.

No those two things and then we can go from there.
