Sample Solution—Thrill of the Ride (continued)
To find the steepest part, we could find the maximum value now in L L ist 3;
however all positive slopes are necessarily larger than any negative ones,
which indicate downhill slopes. This leads us to two options. We could find
the absolute values of these slopes, or simply find the maximum and the
minimum values. We have chosen to do the latter, finding the maximum in the
first entry in L L ist 4 and the minimum in the second entry in L L ist 4.
To do this,
We typed in MAX-MIN in the S S UB area of L L ist 4 to remind us what these
values are.
With the cursor in the first entry of L L ist 4, if the screen has
