How to easily and accurately find intersection points on graphs

[JDW]

Please know that I appreciate the suggestions. But it’s still a lot of trouble.

My daughter actually showed me an app on her iPad that allowed her to merely tap near an intersection point and it would automatically jump it’s crisshair to the exact intersection point and show the X and the Y values. Since we are allowed to tap on the Prime, it would be nice if the graphing app could be updated to add this great convenience feature. And I would also propose that once you tap and once it jumps the crosshair onto the nearest intersection point, you should then only need to press the circular movement button once to jump to the next contiguous intersection point and press it again to jump to the next intersection point in so on.

Although it is possible to rethink equations as you suggest, there are prudent reasons for the sake of speed and productivity to improve the app.
