Don't do this. Freehanding on a table saw - especially a taper cut - is asking for serious injury. If you're comfortable with using a table saw and have a good cabinet saw, the suggestion to make a taper-cut jig is the best. If your table saw is a contractor saw, don't even attempt it. Contractor saws aren't very precise, and their outfeed tables are way too small to support your work well. You could rig up some horses to serve as outfeed support, but it's still kind of flimsy.
If you don't have a cabinet saw and aren't familiar with using a table saw, I'd go with the jigsaw suggestion. Scribe the casing to the wall then follow the line with the jigsaw. Try to angle the cut back a wee bit to get a good tight-looking fit up against the wall. If you've never scribed before, google for a tutorial; there are plenty out there.
Edit: Actually, even if you have a cabinet saw and are good with it, the taper-cut jig probably isn't the best idea. Chances are it's not a perfectly straight taper from 2" to 1.5". It probably has some curve and imperfection to it. Scribing is your best bet.
