Hi;

1) It is not incredible.

2) I was a genius but then I got stupid.

3) Who is this bobby fellow? Do I know him?

I am glad you got it and soon you will be doing those yourself.

You are still a genius =d

]]>We are getting there just a few more steps:

Divide both sides by (1-n)

Now you use the identity:

We are done!

]]>Oh my I think we are close.

So from there, I divide by -1 to get

-Pi(n-1)/P = nw/P

So -Pi/P = nw/(n-1)P, but there is a negative on the LHS which we do not want?

]]>Everything is going fine.

These are the two steps so far:

becomes

]]>No, do not multiply by the P. Instead split the fraction up like this:

Ok thank you, I have now done that. The only next step I can see is to write (nw/P) + (Pi(1-n)/P)=0.

Then I am stuck again. I am really sorry I am not getting this faster I do apologise

]]>Remember that has a zero on the right so it is really:

Yes! So we can multiply across to rid the P, but then we need to divide again by P to get the required expressions? So there is no need multiplying across?

]]>Hold on you are going to fast. After the multiplication of the two terms you should have:

Yes, I have this!

]]>Hi;

When I divide the first term by it, it becomes simply (Pi/P).

When I divide the second term by it, it becomes: -((Pi-w)n)/PYou mean multiply instead of divide, and you are correct up to there.

Yes, sorry again. I do mean multiply.

What have I done wrong after? I really do not know what is going on, I have spent hours here.

Alternatively I try multiplying the P across from this step: So (Pi/P) -((Pi-w)n)/P = 0

To get Pi - (Pi-w)/n = 0. Then it leads to the same thing, as I divide by P later to try to get the Pi/P expression. These two ways seem equivalent.
