Oblio said:either way i don't see how i won't just get 1/1 = 1...
Right... you get the integral of dz, which is just z. z = arcsinh(x), since x = sinh(z).

Oblio said:I had accidentally switched some z's for x's... that's a bad thing. lol
I get it.
The only thing that seems odd now, is
WHY can one just say x=sinhz? Was that shown in the question somehow already that I'm not seeing?
Oblio said:So, am I correct in thinking though, that this is only true SINCE x =sinhx.
I mean, they made it a 'Hint', but that definition of x is completely necessary to solve it, isn't it?
Without the hint, it couldn't be done?
Oblio said:I guess I mean, it should written that the statement is true WHEN x =sinhz. (made a typo above i see)

Oblio said:Ok, switch x for z.
Was it necessary for the question to define z?
