I used only one variable.

From the partial fractions, I wrote the two series and added them.

Oh yes, I remember your solution now. Do you know that was the first tough problem I worked on when I first joined. I was very tentative back then and when I solved that problem without Jane or mathsyperson finding an obvious error I began to gain confidence in the way I did things.

Sometimes! The ones that you solve in a day or two are fun. But there are those that last for years. Nothing you try works, I have a number of those.

True!

Nothing is better than a problem that falls apart to a method only you know!

I am going to take a little break, see you then.

Hi bobbym,

Okay.

Are you really working on 6?

I feel 6 and 8 are the easier ones, relatively.
