Is there any relation between sin function and hyperbola? Because we have hypebolic functions. Why, how and what way they defind it as exponential form?

i think u can find important applications of these functions in non euclidean geometry.in hyperbolic geometry,these functions are used as metric functions and that's why comes the name hyperbolic
