But thank you so much, very helpful.

But when you're doing U substitution, dont you change the intervals that your evaluating on?

@litcy02 Yes you are correct. In this case I back substituted for u before I evaluated.

If i did not back substitute then, as you suggest, I would have to change the intervals.
