Why doesn't #Mathematica simplify sinh(arccosh(x))? Because apparently, it takes a PhD in #Trigonometry, a magnifying glass, and a deep existential crisis to venture into that rabbit hole. 🤔🔍 Just when you thought it was all about cosines and sines, hyperbolics crash the party and demand their own dissertation. 📚🎉

Why Mathematica does not simplify Sinh[ArcCosh[x]]

When Mathematica seems to not to know how to simplify an expression, it may be doing the right thing, being more sophisticated than you expect.

Oh wow, a blanket! 🤯🧵 Let’s take a mathematician's #poncho, reverse-engineer it, and call it groundbreaking. Because who doesn't want a #cozy #hyperbolic surface to #quest #for the meaning of life while counting pentagons? 🤪🔍

Photograph composed in absolute sunrise in SR SA in one of our beautiful districts.

My next Digital Camera Body should be able to do this kind of composition also
I have been restricted to do this on Android phones, for the last couple of years.

Here is a jigsawpuzzle based on the right-angled pentagon tiling of the hyperbolic plane I designed.
