Why do business calculators have log/exp but not basic trig functions?

If HP going to make the update for the 40th Anniversary maybe on the HP-12C Platinum Edition that 2 functions should be added. I hope.

That's an interesting list Gamo. In my perspective, the TVM solver can handle the Cost, Price, Markup, & Margin so I find myself not needing that. But I do agree with the combination + permutation. Thanks for sharing Gamo.

Gene. Thanks for the reply. I learned a lot about the HP 10bii+, a calculator I can't try out beforehand via emulator. However, I enjoy RPN and programming so I don't think I'll buy one. I'll stick the the 12C, especially since the Voyager series is my most favorite calculator series of all time.

Really all I would like is built-in trig functions, partial-year depreciation, and being able to use multiple programs without remembering program lines. But I don't think any of these suggestions are practical and necessary.
