I am supposed to show that sinh : R -> R is bijective and I'm a bit lost. I suppose the part of showing that it's injective isn't so bad but I'm having some problems with showing that it's surjective. I know the definition of a function being surjective of course but I really don't understand how to apply it here, grateful for any help I can get here.
