Can the following be solved forbin terms ofx?

I post in this forum because the subject equation comes from evaluating the (arc length) integral

,

and also becausesinh(x) is a very calculus-y function.

Thanks,

That is the entire original question. It didn't come out of a textbook, if that's what you're asking. Here's a graph of superimposed on :

Gold is the former, green the latter. Essentially what I'm trying to do is find an inverse function for .

Maxima (my computer algebra system) is unable to solve the original equation for*b*in terms of*x*.

EDIT: sorry... I sorta implied it in my original post, but I guess I should be more explicit. is the arc length of the function from 0 to some*x*. - October 19th 2010, 02:38 AMmr fantastic
