RE: HP-50g derivatives

I got the correct answer by doing the following keystrokes in RPN mode...

[ALPHA] S [LS] [X^2] [ ' ] [ALPHA] T [STO>] [ ' ] [ALPHA] T [ENTER] [ENTER] SIN [Right Arrow] [RS] [ ∂ ] <-- (Orange function above the COS key) [RS] [ALG] [EXPAN] <-- (F2 key)

Which gives me COS(S^2)

If you wish to do this in ALG mode, do this...

[LS] [X^2] [ALPHA] S [Right Arrow] [STO>] [ALPHA] [T] [ENTER] [RS] [ALG] [EXPAN]-->(F2 Key) [RS] [ ∂ ] [ALPHA] T [LS] [ () ] SIN [ALPHA] T [ENTER]

[RS] = The orange shift key, [LS] = The white shift key, [ ' ] = The Tick key

In ALG mode, it's essentially the derivative function using the HP 50g's keyboard is inside the Expand function. In RPN mode, just make sure to use the Tick key to make sure the T does not turn into S^2. I get COS(S^2) as a result for both methods. Let me know if there are any questions or confusion on my keystroke examples above. I used the HP 50g 2.15 version so it should work.
