Understanding Hyperbolic Functions

[lch7]

Will someone help me to understand sinh, cosh, and tanh. I know they have some relevance to hyperbolas and trigonometric identities. Thank you.

The main reason to use these is to give a shortcut for derivatives of variations of e functions. There is no need to learn these until calc and not. even necessaru for calc since you can always do it out instead of wrote memorization.
