My son has been working on finding equations for the length of a curve. He is in prison and does this w/o access to computers. Could someone please look at the attachment and see if he is on the right path? Thank you, mathematicians, for I am ignorant in math and cannot help him. Any legit feedback would be greatly appreciated.

I have to confess I don't really follow what your son is doing in his text.
I attach a small pdf on the subject and a pdf of my own.
