Re: Fancy Leather Cases

I did at one point and had some nice cases made both for printers and calculators.

The guy who made them was later convicted for child molestation and is spending a long time in gaol. A good thing IMO.

Re: 43S News

There are spaces in both the EXP and TRI menus, so we're not losing anything. Unless we start adding sec, cosec, cot and their hyperbolic equivalents :twisted: Jacobi's sn an cn are related to sin/sinh and cos/cosh respectively, so they might be a problem adding to the TRI menu (like sinh/cosh). The...

I don't really count x^2, I use square root far more often. To my mind x^2 is for programs, ENTER * is a nice and quick sequence and I rarely need to maintain the top of stack when I'm computing by hand.

Re: 43S News

I came up with a third possibility overnight. Instead of y^x in the blue shifted location, we could add a new menu for elliptic functions. These functions bridge the gap between hyperbolic (in EXP) and trigonometric (in TRI) so would be a natural fit there. What would be in such a menu: The differen...

Re: Spots on display, not pixels

A second cooking in the range 80℃ to 90℃ an the last dot has come good. My DM 16C is happy again.

Re: Spots on display, not pixels

I spoke too soon, the device came out of the oven about seven hours ago and one black pixel has returned. I'll give it another heating cycle and see.

Re: Spots on display, not pixels

My DM16 exhibited this problem and I tried Michael's solution: baked in our over at around 80℃ for a couple of hours. I let it cool and the marks are gone. I've not powered it up yet but will soon.

I didn't know LCDs did this.

Re: ROT XY on Floating Point numbers

Why 52 bits when using binary reals? 53 should be possible.

Re: 43S Alternative key layout --> WP43C

I understand the problem now: you're trying to display the cumulative integral.
The horizontal line segments seem like a reasonable idea as might joining the corners of the squares in this image. The integral and the function should only interfere in a small number of places.
