Re: [50g] newbie eqw question

I can't follow the code you gave, never used a 15c.
But if you want to evaluate a function for values you
enter individually, one of the many ways is to
"define" a softkey for it. Say the function is
f(x)=sin(1/x). Enter it as 'f(x)=sin(1/x)' by pressing
the '' key first then typing in the function followed
by enter. Then press the def key (left shift 2 on the
49g, probably the same on the 50g) and you should see
a soft key labeled f. Now to evaluate the function at
3 just press 3 and then the f soft key.

To enter a program press the <<>> key and enter the
program between those delimiters. Press enter and the
program will be on the stack which you can then store
under a variable name of your choice. You'll really
need to RTFM to learn programming.
