Intersection Option
The intersection option is used to determine a point of intersection
of two graphs. While viewing the graphs, press
to view the math menu.
Move the cursor near the desired point of intersection and
press 
to select the intersect option.
The coordinates of the point of intersection appear at the bottom of the screen
and are added to the stack.
Here, the point of intersection is about (1.548 , 0.677).
Note: If there are more than two functions the HP will find a point of intersection
between the first two functions. To rotate through functions select
Next Equation by pressing 
in the math menu.
The first equation will be put at the end of the list and all others move
up one spot.
