HP-50g Syntax Question - Daniel Greenidge - 03-28-2012
Hello,
I'm trying to plot a basic sine curve with the HP-50g (which it does very well). However, I'm running into some trouble when I try to change the tic marks on the x-axis to appear at intervals of Pi/2.
Here is my procedure:
1. LSHIFT 2D/3D
2. Cursor down to the "pixels" option
3. Uncheck it.
4. Cursor left to "H-Tick"
5. Enter this expression 'Pi/2'
6. Press enter.
It then throws up a "Bad Argument Type" error.
Any help would be appreciated.

HI.
The correct expression for Pi would be PI (all upper-case letters). Also, check if approximate mode is active.
Cheers.

Hello Luiz,
Approximate mode is active, and I tried both "PI" and the symbol pi (LSHIFT SPC).
Still no luck.
Thank you for your help though!
Best Regards,
Daniel

After putting in the expression 'pi/2' (using the Greek character ALPHA L-SHIFT SPC), press right-arrow to get past the closing quote and press EVAL before entering the expression.

Another way to do it is
Pi 2 / ->NUM
