Integral in solve on HP 42S?

Code:

00 { 30-Byte Prgm }
01▸LBL "∫f"
02 MVAR "ACC"
03 MVAR "LLIM"
04 MVAR "ULIM"
05 INTEG "x"
06 10
07 -
08 END

.. makes it a lot easier to enter the numbers, and to play with different ACC's.

Cheers, Werner

Would anyone want to SOLVE for ACC though?

A useful thing to add would be the (signed) area, which is fixed at 10 in the above versions of ∫f.
