I can see I've missed the negative which changes it quite a bit. Is the integration by parts correct for C=1? It hasn't really solved the integral, or am I missing something here?

Thank you for the quick reply. I'm also asked to explain how I = 1/2 can be true, when using substitution yields ln(ln(x)). This is basically where I am stuck. Thank you
