Homework Statement
I need to fit a curve using cosh to a hyperbola with a vertex of (0,0) and a point at (4,7).

Homework Equations
[tex]y=a cosh (\frac{x}{a})-a=\frac{a}{2}(e^{\frac{x}{a}}+e^{\frac{-x}{a}})-a[/tex] "is the formula for a hyperbola at a vertex of 0,0. a is a constant that modifies the shape" that is what the assignment said exactaly
The Attempt at a Solution
I plugged in 4 for x and 7 for y and attempted to solve algebraically, I just got stuck. then I plugged the equation I attempted to solve into wolfram alpha and got the response no integer solution.
