Replacing 5 SQRT 1 + 2 / with 0.5 ASINH E^X saves three lines, so that leaves 11, not counting the LBL and the END. How do you eliminate another two lines? EDIT: oh wait, it's easy to eliminate one more line by replacing the E^X X<>Y Y^X with * E^X. But that's still one line longer than the challenge... |
