Re: Any experience with changing the feet?
Here same problem. My 'solution' is to rest the machine on top of its empty case while using...seems to reduce the wobbly feel.
Re: LOG bases
That’s not a HP 42s trick, but a gaping gap in my fundamental knowledge and understanding of math in general and LOG / LN in particular!
I’m dedicating tonight to trying understand why LOGb(x) = LN(x)/LN(b), but indeed: no solver required!
Learning something new everyday, thank you guys!

Re: LOG bases
Thank you. Interesting solution
I now use the solver and solve b^e=x for the exponent e, which works as well, but I just wondered if there was a trick to use LOG with a different base without resorting to solvers or programs. Apparently not.
Thanks for your reply though!

LOG bases
hi all,
This may be more a general HP 42s question, but is there a way to use the LOG function with different bases?

Discrepancy between DM42 and Hp 50g
Hi all, I posted this on the HP forum as well, but since it also relates to the DM42 I thought I’d ask here too. I hope you guys don’t mind. Today I calculated the energy flux from the sun using the Stefan Bolzmann equation: EF = sT^4. So as follows: 5777 4 Y^X 5.67E-8 * On my DM42 and WP34s the res...

Re: remove program/function from custom menu
Even better!
And thanks for the reference to the 42s doc! For some reason I completely missed it!

remove program/function from custom menu
Hello,
I've put a few programs and functions on the custom menu of my DM42. Now I'd like to remove some of them, but I can't seem to find a way.
Is there a way to empty the custom menu or otherwise remove menu items from it?

Re: Broken key
Mea Culpa...my intention for this post though was to ask about the defect itself, while the post in General was specifically about the supposed lack of support.
I'll keep it in mind though.
