Piecewise function can be entered using Mathematica syntax, for example,

http://www54.wolframalpha.com/input/?i=Piecewise%5B%7B%7B1%2Cx%3C0%7D%2C%7B2%2Cx%3E0%7D%7D%5D

and then it can do integrate, etc, using this

http://www54.wolframalpha.com/input/?i=integrate+Piecewise%5B%7B%7B1%2Cx%3C0%7D%2C%7B2%2Cx%3E0%7D%7D%5D+from+x%3D-1+to+x%3D2

but there should be better way….

Thanks, Jay. This is actually pretty handy. I like that the integration comes with a shaded graph to help visualize it.

integrate Piecewise[1,x<0},{2,x>0] from -1 to 5 does the job very easily. (But I learned this using Jay's form as a starter.) However this fails if Piecewise is not capitalized. I sent a suggestion in this direction to W|A.
