How can I rewrite arcsinh(x/3) in terms of ln ? I know that arcsinhx = ln (x + sqrt(x^2 + 1)) but I can't figure out how to rewrite arcsinh(x/3) in terms of ln.

The way I'm doing it right now ends up giving me 3arcsinhx instead of arcsinh(x/3)

EDIT: Nevermind, I'm an idiot. Its just arcsinh(x/3) = ln ( x/3 + sqrt((x/3)^2 + 1))

Was going to say, the "in terms of" is misleading, it simply means have ln in your answer.
