    \dfrac{d}{dx} [arccosh(u)] = \dfrac{1}{\sqrt{u^2-1}} \cdot \dfrac{du}{dx}

    Agin, like many of the others, it is a simple application of the chain rule and a standard formula for the derivative of arcosh. (If you are familiar with functions such as arcosh(x) you should surely be familiar with basic techniques of differentiation).
