– 2 –• 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 thecenter. Repeat this step a number of times and use !1(TRCE) e to move thecursor closer to the intersect point and produce a more accurate value.SummaryIf, 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 furtheradjustments, if required.E-1 Speed and Distance
