I seem to have got stuck up with an apparently simple problem with the symbolic toolbox. Would appreciate help in solving this.

syms x y
% I want to integrate a second derivative

I am trying to follow a derivation in a textbook. There, the answer seems to be :
1/2*(dy/dx)^2. I would have thought that it was (dy/dx). I get an answer of 0 from the above code. What is my mistake in coding? Would appreciate it if somebody could point out the error in my understanding also.
