ti-83 sin graph problem

Hi;
When I graph sin(x) I can't get the y values to come out right ie give a zero value
when on the x coordinate using trace.

That sounds like a resolution issue. If you zoom in to the root, you might get closer to what you want.

Yeah thats get me close is there a way of seeing the whole graph with correct values?

Thanks.

Sometimes you can fiddle with the limits of the window. Instead of going from 0 to 10, say, you go from 0 to 2pi. The tracer might be sensitive to that, and go along the curve in increments of, say, pi/32. I don't know. Other than my two posts, I know of no way to do what you want. Zooming in on graphs is a standard trick.

ok thank you.

You're welcome!
