A very nice "engineer's demonstration" with no understanding of the underlying mathematics. (e.g. a catenary isn't a parabola). Brilliant stuff!

@jsiehler cosh 𝑥 and sinh 𝑥 have the same right to exist as cos 𝑥 and sin 𝑥 because they all together appear in the matrix representation of a four-dimensional Lorentz transformation. The hyperbolic functions describe the acceleration in the same way as the ordinary trigonometric functions describe a rotation.
By the way, are there other “natural” uses of the hyperbolic functions?
