I wonder how I can compute hyperbolic terms like cosh(ln2). The calculator we're allowed to use doesn't have buttons for calculating hyperbolic functions.

The hyperbolic trig functions are just sums and ratios of exponential function.

type hyperbolic function on wiki or something.

Incidentally, your example is trivial, if you know that

$$\cosh x =\frac{e^{x}+e^{-x}}{2}$$
