OK this one was kinda obvious but usually that is where I make the errors especially where there is substitution.
I post another one here soon.

That all looks correct to me, except that at one point in the solution of 6.6.62 you have written $du=dx$. That should be $\dfrac{du}4 = dx$ (which is what you have correctly used in the following line).
