• Keep pressing e until the cursor is at the point where the two graphs intersect. This pro-
duces values that provide an approximate result for the exercise.
• Press
2(Zoom) and then 3(IN) to enlarge the graph with the cursor location as the
center. Repeat this step a number of times and use !1(TRCE) e to move the
cursor closer to the intersect point and produce a more accurate value.
Summary
If, when you use other formulas for the above exercise, the graphs do not intersect, try in-
creasing the X-axis and Y-axis ranges. Check the results on the display and make further
adjustments, if required.
