How to solve this problem.
Below program:

Code: Tout sélectionner

prgm
Input "X1", A
Input "Y1", B
Input "L1", L
Input "X2", C
Input "Y2", D
Input "L2", R
solve((X-A)^2+(Y-B)^2=L^2 and (X-C)^2+(Y-D)^2=R^2,{X,Y})
EndPrgm

Does not display results. It should display two pairs of solutions. The HOME line displays correctly and the program does not. How to remedy this.

It's been a decade since I programmed in TI-Basic, but have you tried the likes of "Disp solve(...)" (without quotes) ?

[Longines]

disp solve((X-A)^2+(Y-B)^2=L^2 and (X-C)^2+(Y-D)^2=R^2,{X,Y}

displays

X = 51.86 AND Y = 17.56 OR
More can not fit on the screen, scroll also can not.

I'm a bit late but here is an answer.

If you want to be able to scroll along a displayed result you have to use Pause result.
The program will be stopped until you press "Enter" and you will be able to scroll using the arrows.
