I remember seeing hyperbolic trigonometric functions (sinh, cosh, tanh, etc.) in my precalculus textbook back in high school and see them today in my calculus textbook. However, I have not had a formal introduction to them in my education. This may just be with me, but I would like to know if there is a reason as to why they are avoided.
