Did you complete it?

Hi gAr;

It was not necessary as I already did that one and you showed me your solution. Not only did I forget the solution, I forgot that I already did it.

Hi bobbym,

I showed only the solution to the integral. Did not know you completed it.

Congratulations! Which was the other one you solved?
