There isn't enough space to put two brackets in, is there? Re: [43S] Display and top row, refined - Paul Dale - 04-22-2013 I wonder why?? ``` (LN(1)) + x = 0 + x = x ``` Kind of pointless. The LN(1+x) function is absolutely vital to producing correct results for many financial and statistical computations. - Pauli Re: [43S] Display and top row, refined - Walter B - 04-22-2013 Quote: There isn't enough space to put two brackets in, is there? Yes it isn't. d:-) Re: [43S] Display and top row, refined - David Hayden - 04-22-2013 What if you used the smaller font? Maybe LN(1+x) or ln(1+x) Re: [43S] Display and top row, refined - Thomas Klemm - 04-22-2013 What about: x1+LN ? Re: [43S] Display and top row, refined - C.Ret - 04-22-2013 What's about LNP1 such as on HP-28/48/49/50 soft keys ? Re: [43S] Display and top row, refined - Ángel Martin - 04-22-2013 LN+1 LNx+1 Re: [43S] Display and top row, refined - Harald - 04-22-2013 Pauli, of course I am aware that (LN1)+x would be completely pointless. Still my brain would like to see LN(1+x) instead of LN1+x. Re: [43S] Display and top row, refined - Bill Carter - 04-22-2013 Walter- It's looking very nice! Two questions: 1. Is there a symmetry (or other) reason for having x^2 as the primary function and SQRT as the yellow-shifted function instead of the opposite? I generally just do ENTER *. This is easy, and it's very rare (when I'm worried about losing something from the top of the stack) that I use x^2. In contrast, there's no way around SQRT. 2. I thought in the last thread you had settled on leaving the top row blank, rather than labeling them F1 ... F6. Maybe I'm mis-remembering, but I left that discussion contemplating how I might re-label (engrave?, paint?) the top row keys. "Factory" labels won't preclude that (unless the keys are double-shot!), just add a step. -Bill Re: [43S] Display and top row, refined - Eric Smith - 04-22-2013 I agree that I'd much rather have sqrt as the unshifted function. Some time back I requested that the top row keys have no legends, rather than F1..F6, but at the time I don't think anyone else expressed support for that idea. Yes, Sqrt rather than x^2 as unshifted - Gene Wright - 04-22-2013 IMO of course. Just look at it - Walter B - 04-23-2013 Just look at the new HP Prime keys. Of course that may be necessary though not sufficient. d;-) Re: [43S] Display and top row, refined - Eddie W. Shore - 04-23-2013 Looks good. The screen looks sharp. Re: Just look at it - Gene Wright - 04-23-2013 Hey, I expect you guys to fix the things HP gets wrong. :-) Re: Just look at it - Bill Carter - 04-23-2013 Yes, I'd say HP missed on that one. I'd be curious as to any reasoning for the change from past efforts (15C, 42S, 48G, 35s, etc.). To my thinking, they tinkered with something that worked and ended up with a less useful result. -Bill Re: Just look at it - Tim Wessman - 04-23-2013 It makes sense if you are targeting students. x^2 unquestionably is used more there then sqrt based on all data I've ever examined. Personally, I think it is stupid since it is just a ^ 2 but there you go. Re: Just look at it - Gene Wright - 04-23-2013 And, Tim is almost certainly correct...for students. Having two keys for x^2 and x^y pains me, but there you go. :-) However, for the 43S, we face no such constraints! lol Re: Just look at it - Bill Carter - 04-23-2013 OK, fair enough: it's one difference between a tool optimized for teaching/learning and a tool optimized for professional use. Targeting the intended market makes sense in the case of the Prime and the 43S. HP will (hopefully) sell more Primes to students, while the 43S is targeted squarely at a small subset of professionals/enthusiasts who understand the other ways to get to x^2. -Bill Re: [43S] Display and top row, refined - Reth - 04-23-2013 x^2 as primary is plain wrong for a RPN/RPL machine. Surely sqrt should be there. Re: [43S] Display and top row, refined - Walter B - 04-24-2013 Assume x^2 and SQRT swapped. d:-)
