Calcuator forensics history question

29 sin cos tan ln 1/x 1/x e^x arctan arccos arcsin.

It adds a few more operations, in other words.

I was wondering if anyone else remembers this and if so, where it might have come from?

(For the record, my WP34S returns a value of 29 in double precision mode, and my HP Prime gives 29.0000023889 -- exactly the same as my HP 27S -- and my TI 36X Pro yields 29.00000017.)

The TI-36X Solar gives 28.99999928
