Question

Answer 2

Hmmmmmm, it looks correct. How do you know it's wrong? Do you have a book answer? Or an online thing not accepting it?

It's an online thing not accepting it...

Answer 4

The only goofball mistake I see is that you changed your hyperbolic secants into secants halfway through (I do that all the time lol). It's so easy to just drop that h lolol

Answer 5

Oh that would probably explain it then :)

Answer 6
