Set parameter bounds for improper integral

[carey]

Thanks Tim for your help!

If you are referring to the 3rd screenshot, it shows the CAS output that displays after clicking Enter from the CAS input (screenshot 2) where there is a space separation after the dt. (I'm curious why the CAS output doesn't seem to reflect what was entered in the CAS input template but will save that question for another time).

I'm sure I am making some silly syntax error but am still at a loss as to what it is.

Thanks again!
