Ti-Nspire Graphing - radians

[Dean]

I am interested in knowing if - when graphing trig functions - one
can have the x-axis in terms of pi. I know that one can set the x-
scale to say pi/4, but that still gives decimals on the x-scale. I am
interested in LABELS that read pi/4, pi/2, etc. Can this be done? How?

Thank you for your help
Dean

Yes, but by hand:

- Change the settings to have tick marks every Pi/4, Pi/2 or whatever
value you want;
- Create a point in each tick mark (not the axis, over the tick marks
exactly. Check that they're well created by dragging them around. If a
point is created over an axis it will move continuously. But if it was
created over a tick mark it will jump from one tick mark to the next.
- Label those points with the corresponding values. Pi/4 will display
nicely as a fraction;
- Change the attributes of each point to be only a small dot, so that
they're almost invisible;

Extra: while changing the attributes of the points, lock them so that
they can't be moved around by accident. It would be weird to have a
point labeled Pi/4 showing at x=Pi/2.

Not a very elegant solution, but it's the only one I can think of...

Cheers,
Nelson

G&G is inherently approximate. You can set it up to pretend like it is.
1. Window > Setttings ... make the scale pi/4 like you said.
2. right click on the axis (ctrl menu). Change the Attributes of the the axis so the decimal pi/4 doesn't show up.
3. menu > Point On ... put points on the axis and, like you said, label them pi/4, pi/2, pi.
  Move them to where they belong and change the attributes to the little crosses.

Hope that makes sense.

Yes, lock them like Nelson said. :)

Thank you very much - I was going there, but I was wondering if there
was an automatic way. Well, this clears it up.
