F' on hp 15c le
Can't remember program using complex capability of hp 15c le to solve f'x = 0 in order to find a max/min of f'x.
This was from several years ago...somebody contributed a real neat short elegant program! f(x) is defined in program 0, f'(x)would be in program 1, dx in register .0, "x" result in program 1 would be plugged into program 0 to find f(X) at that point. |

That's the one!
I'm glad that the post included my struggle to understand the problem with using change sign with complex numbers as well...would have forgotten that! |
