Title: TI-nspire Graphing Vertical lines, e.g. x=1
Post by: d-ea-6 on November 06, 2010, 06:56:25 pm: Does anyone know if you can graph vertical lines on the TI-nspire? i.e. x=1 or 2 or 3... etc

If so, how :P

Cheers

yeah, but if it could find coordinates in exact form, then it would be even more sexy ...

And yeah, thats a fairly sweet method.

OMG TRUE! That would be the climax of having a TI-nspire CAS ;) <3

Click anywhere to add the point.
Use contextual menu to add in the coordinates.
Menu, Geometry, Construction, Perpendicular then select the x-axis then the point you just added (it doesn't show the whole line, only a section nearer the point, but it is there). Remember to hit escape to stop the construction process so it doesn't try to add any more perpendiculars (the icon disappears from the top left corner).
Double click the x-coordinate of the point you created and change the value to move the vertical line.
You can use the line to find intersection points with Menu, Geometry, Points and Lines, Intersection Points then click on the line you created and another function you want to find the intersection point of. It will automatically extend the line to where it needs to if you do this.
