How do I use calculated values from FCN or STATS in the HOME view?
For example, you wish to find the intersection of F1(X)=1/X and F2(X)=LOG(X) as accurately as possible and then use this in a calculation. Enter the two functions into the SYMB view, change to PLOT SETUP and press SHIFT CLEAR to reset to the default axes and then press PLOT. On the resulting graph, move the cross-hair to a point near the intersection and then use the FCN menu to find the intersection. The value quoted at the bottom of the screen is accurate to 7 dec. places. Now, without doing anything else, change back to the HOME view and type X and press ENTER. The value which appears is the stored x coordinate of the last intersection point found. To find the y coordinate, evaluate F1(X) (or F2(X) – for that point the values are the same). This value can be used in calculations in the HOME view (such as 3*F1(X)+1 or LN(X)). If you’ve found a Root or Extremum then you can do the same thing. If you’ve just used the FCN menu to find a Slope or Signed Area then you can also retrieve th
