Problem ti-nspire

[Vivek Raghuram]

Hi,

When I graph regular functions on my ti-nspire, things seem to be fine. But when I graph sin(x) or tan(x), I get a straight line instead of the waves. I think some setting is messed up but I don't know which one. Please help!

Have you changed to degrees?

Also try menue>window/zoom>zoom-trig.

Last, make sure use are graphing for x, and not a value.

Thanks Ray.  It was zoom-trig that caused the problem.  So whenever I have to do trigonometric functions, I need to change my window settings to trig? Or is there an automatic way to change from regular functions to trig?

That is the easiest way I've found.

Maybe someone else has an easier way.

OK thanks for the help.

On a Graphs app on a handheld, press menu and select Settings.

The Graphing Angle is Radians and the Geometry Angle is Degrees by default.

 

If you change the Graphing Angle to Degrees then Zoom Trig will not display what you expect because the Trig window assumes Radians.

 

Remember that Graphs and Geometry are the same app with different views (you can change the view on menu>View).
