How to draw 'Integral (0,20, SIN(X)/X,X)'
with the HP50G?

1. Set the Mode to RADIAN

2. Define the Function to be plotted
Enter '∫(SIN(T)/T, T, 0, X)' (Algebraic Mode)
Store the function in Variable 'EQ'

3. Configure the Plot:
Goto "Apps", 1. Plot Functions -> 4. PLOT SETUP -> choose FUNCTION

4. Configure Plot Window
Goto "Apps", 1. Plot Functions -> 2. Plot Window:
choose your plot window according to your needs (x-, y range etc.) or use "AUTO"

5. Create the Plot:
Goto "Apps", 1. Plot Functions ->3. Graph Display

Good luck!

Thanks for the explanation.

I forgot to store the function in EQ.

Now it works perfectly.

It works similarly with an HP-48.
However, you have to store the following formula in EQ instead:

'∫(0,X,SIN(T)/T,T)'

I just hit ↱ PLOT, set H-VIEW and check AUTOSCALE:


And then hit DRAW:
