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

The question asks to solve by substitution, which I can do and results in ln(ln(x)) + c
It then asks to compute using integration by parts, and then to explain how it can be true (because...
