Hi lordb,
In normal FUNCTION graphing mode, you can't graph a line in terms of x. However, in PARAMETRIC mode ([MODE] -> Expand dropdown, select PARAMETRIC), you can graph in terms of either x or y. In parametric mode, you graph x and y in terms of a third variable t. So for instance, a graph in the form of x=n, would look like
You can also graph a function in the form of y = f(x) in parametric mode by using the following:
| Code: |
xt2 = t
yt2 = f(x) [some function in terms of x]
|
That way you can combine and display multiple functions on the same screen, some in terms of y, and some in terms of x.
Hope this helps!
Regards,
