Chapter 5, Problem 21P
Integrate the algorithm outlined in Fig. 5.10 into a complete, user-friendly bisection subprogram. Among other things:
(a) Place documentation statements throughout the subprogram to identify what each section is intended to accomplish.
(b) Label the input and output.
(c) Add an answer check that substitutes the root estimate into the original function to verify whether the final result is close to zero.
(d) Test the subprogram by duplicating the computations from Examples 5.3 and 5.4.

Information about ocean weather can be extracted from radar returns with the aid of a special algorithm. A
study is conducted to estimate the difference in wind speed as measured on the ground and via the Seasat
satellite. To do so, wind speeds (miles per hour) are measured on the ground and via the Seasat satellite
simultaneously at 12 special times. The data is shown in the following table. The table also shows the difference
between the wind speed on the ground and that via the Seasat satellite at each time, as well as some summary
statistics.

On the 4th night after he started the diary, AJ slept 9.4 hours, which was the most sleep he got any night. Gradually, he got less sleep each successive night until, on the 18th night after he started the diary, AJ slept 6.2 hours, which was the least sleep he got any night. After keeping his diary for 6 months, he realized that the number of hours he got each night followed a sinusoidal curve. Let t be the number of nights since he started his diary, and s be how many hours he slept that night. It may be helpful to draw a crude sketch of the sleep time function and label the known t − and s − values on it.
