Can anyone please tell me where to go with this problem.

A chain hangs in a shape called a catenary, the equatio of which is;

f(x) = a*cosh(x/a)

Determine value ox when f(x)=48 and a=35.

Thanks in advance.

I'm still none the wiser, I need to know how to get x on it's own.

I'm struggling with this one. - August 9th 2009, 12:14 PMRandom Variable

Hi, I have tried that but when I place the value of x back into original formula it doesn't come back to f(x)=48.

Sorry, I,ve got it now.

I wasn't putting it to calculator correctly.
