Sorry, but this feature isn't available on the 49 yet. :-( I, for one,
hope it will be implemented soon.

Hello

Equations in ROM 1.16 don't get erased.. They are simply saved in the
current directory. You can re-add it by simply pressing the CHOOSE button

Let say you type ADD:
Y1=x+3
ADD again:
Y2=2X
ADD again
Y2=2X^2

Now, either you draw them or press ENTER

If you jump back in the Y= window you can simply delete from the Y= view the
equation. You can always put them back by pressing the CHOOSE button

Hope that help
Jean-Yves

Sent this before but i did not see it posted.

write a small program
<< x 3 > 'x^2' 'x+2' IFTE >>

or multiply by a test
(x^2)*(x>3)+(x+2)*(x<=3)
