In that case, all you need to know is that "hyperbolic" trig functions cosh sinh tanh sech coth and cosech work almost
the same as ordinary trig functions (for example, sinh(2x) = 2sinhx coshx), but occasionally you get a + instead of a minus (or vice versa) … I think only when you have two
But, to be on the safe side, use gabbagabbahey
