This is not homework. I've been analysing some space-time diagrams and found I need to know the biggest angle in the illustrated triangle in terms of the lengths and the angle A which are known.(adsbygoogle = window.adsbygoogle || []).push({});

I found the equivalent of the cosine rule of Euclidean space for the hyperbolic plane but I'm confused about the definition of 'Cos' on this plane. Is it still adjacent/hypoteneuse ?

Any hints much appreciated.
