Speedometer readings for a motorcycle at 12-seconds intervals are given in the table.
t (sec) 0 12 24 36 48 60
v (ft/sec) 22 26 29 23 23 30
(a) Estimate the distance, in feet, traveled by the motorcycle during the time interval from 0 to 60 seconds using the velocities at the beginning of the time intervals.
(b) Give another estimate using the velocities at the end of the time periods.
(a) you want the Left Sum, so that is
12(f(0)+f(12)+f(24)+f(36)+f(48))
(b) the RS is just
12(f(12)+f(24)+f(36)+f(48)+f(60))
