Improper Integrals with the HP-15C LE & CE

[Chumango]

I tried this with a 35S and after letting it crunch for a while I interrupted it so as to not chew up batteries. I did this with a DM41X connected to the USB and it took about 2 min 15 sec and gave 1.999870530 when set to Fix 4. On first try it took about 7 minutes, but I noticed after that the USB was not connected. The USB port is very finicky and the cord comes loose very easily (tested with another cord with the same results).

My 41C would probably take a very long time to do this.
