Ok thank you

In conclusion what you are saying is that we can reciprocal the entire thing, but not separately?

Ok. Thank you for all that you did. It did help.

I’m sorry I’m it didn’t make sense, but this is what I’m trying to figure out

Could we do it this way ? 1/1-1-1/(2x)-1+1/(3x2)-1

Yeah but wouldn’t the powers become negetive when you flip them

Can’t we reciprocal first and then factorize?

Ok I figured this out But, what if you do it in reverse? 1-2x+3x^2-4x^3 and reciprocal that? How does the extra parts get removed from the infinit sequence to for a finite one? My main problem is that wish to see the cancellation of those

How did 1/(1+x)^2 Become that? Could you use the example from the question and show this?

Thank you for this. Could you explain a bit more how this form is derived? Im a bit unfamiliar with the (1+(2x+x2))-1 part came from.

Yes I know that. But what’s bugging me is, what if I do the reciprocal after expanding the bracket, them it’s not the same. If I expand the (1+x)2 and i do a reciprocal,(which I still don’t know how) I don’t see how I could get the 1-2x+3x2-4x3…….

1/(1+x)2 and (1+x)-2 are the same but the negative index binomial has an infinite expansion, but the other as a denominator, stops at x 2 So please help me understand this Thank you in advance.

My my my. Such a wonderful explanation. Thank you sir. You’ve made my day

Ok. I’ll ask here the questions may sound a bit stupid, but please humor me. I believe even if it sounds stupid, once it’s explained, stuff becomes clear. Normally when I differentiate stuff, I need to know the whole function, you differentiated this while part of the function was unknown. I...

This is ok, but I’d like to ask the questions and get answers as I am asking them, like a chat. It’s too slow on the forum.
