Hi kenny;
Solve in what sense? For one thing it is not reducible in terms of elementary functions.
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

It's a method to use to answer the question that it relates to.

Hey bob bundy,
I was just answering Kenny's question which obviously is just a combination to use.

hi Alive,
Sorry. 
I hadn't noticed that. I was thinking you were the OP. Apologies.
I look forward to your solution.
