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.
