My iPad emulated is 34S 3.3T 3913

I’m running the program now on my HP 30b that was converted into a WP 34S, and the integral is taking a long time to converge (perhaps 25 minutes into the integration), and it may be converging on the correct answer. The DM 42, and the IPad 34S 3.3T 3913 quickly produce “0”.

I will let the HP 30b converted unit continue to run a while longer. After it finishes (or I give up), I will check it’s version of the WP 34S software.

I used Windows emulator.

I think it is 1/(x^(1/3)), Wolfram Alpha gives 4.31068-2.06209 i

"3 root" is the cube root but "3root" = x^(3/2)
