In the math template menu (the key between the toolbox and the x-t-theta-n key), it's in the top row, 3rd item. You can see its help screen in the Toolbox Catalog menu, immediately following ztrans in alphabetical order (highlight it and press the Help key).

Another approach is to use the 'assume' command, for example:
assume(x>-1)
This tells Prime to assume that x<-1 for all future CAS work (until you change x's assumptions, or delete them, of course). I personally dislike using 'assume' because I always forget that I made assumptions and they cause me trouble later... just like in real life. Big Grin

Before the answer shows up, I get a message saying:

Quote:No checks were made for singular points of antiderivative (x+1)*taylor8^(x+2)/(x+2) for definite integration in [0,1]

Is this supposed to happen?

Yes, this is supposed to happen
