Hello there. I need a little bit of help on one of these questions. I can do 2a and 2b but I don't know where to begin on 2c. Maybe an indication of what to do if that would be really helpful. Thanks in advance.

For i) you should get y using a well known identity, and plug that into the arc length formula?

Hyperbolic identity. Just look at the shape of the wire, that would give you a clue.

y = cosh(x)? Am I on the right track?

Is Y that is in the first equation the same as Y in the cordinates?

Yes, although there are a couple of simple transformations to make it match the given information.
