Crash when Solve for Integral with 15C

That's quite alright. If you had explained it in the initial post, I likely would have just skimmed over it and spent no time thinking about (vs. the little time I did spend, but better little than none!) so by showing just the solution and a hint, it helped me to explore it and learn a bit more.

But in the top line of the notes you show:

u=x^3 -> x=u^(2/3)

Shouldn't x=u^(1/3) ?
