My plan was for i to fill the blank spot on the PI menu, and for there to be a new page in the math menu for complex functions. My math skills are sufficient to implement complex arithmetic in both rectangular and polar (including integer powers), but insufficient to implement complex trig.

The golden ratio was just suggested as a space filler, but yes, i would make more sense if complex numbers are implemented.

Perhaps there are library functions you can access for complex trig etc.

Quote:I've never met anyone passionate about csc, sec, and cot before. I mainly just put them there to fill an empty button. Is there one function that you would most like to see to fill the last empty button? If not, the layout would fit okay with three rows of buttons: secd, asecd, sec, asec | cosh, acosh, sech, asech.

I can't say I've used sec, csc and cot much, but I suggested the extra functions for symmetry with the other trig functions. If choosing between one of asec and secd, I think asec would be more useful, as it's always handy to have the inverse of a function.

Quote:I would have to do some more investigation on gamma function algorithms to determine if this is viable. Do you need the complex version?

Calculating the gamma function for real numbers looks quite complicated, though you may find a library function to do it. Calculating the gamma function of a complex number looks a lot more complicated!
