# Math Help - Hyperbolic Sine Function

1. ## Hyperbolic Sine Function

The hyperbolic sin function, designated by sinh x, is
sinh x = (1/2) (e^x - e^(-x)).

Show that f(x) = sinh x is an odd function.

2. An odd function satisfies $f(x)=-f(-x),$ that's all you need to solve your problem, show your work.

Are you saying for me to replace x with -x in the given function and simplify?
