## Main Question or Discussion Point

I read the wiki on hyperbolic functions but i don't really understand. I also plotted cosht,sinht on wolfram it made sideways v lying on the x axis. Can any one explain why people made hyperbolic functions.

I still don't really understand what it means apart from cosht being the x coordinate of the intercept of a ray passing through the origin intercepts a hyperbola, where the rays angle is 2A
