Chapter 19, Problem 3P
The pH in a reactor varies sinusoidally over the course of a day. Use least-squares regression to fit Eq. (19.11) to the following data. Use your fit to determine the mean, amplitude, and time of maximum pH. Note that the period is 24 hr.
| Time, hr | 0 | 2 | 4 | 5 | 7 | 9 | 12 | 15 | 20 | 22 | 24 |
| pH | 7.6 | 7 | 7.1 | 6.5 | 7.4 | 7.2 | 8.9 | 8.8 | 8.9 | 7.9 | 7 |

CHAPTER 1: HISTORY OF COOPERATIVES AND STATE POLICIES
Questions for Critical Thinking
1. Discuss the different stages in the history of the Philippine cooperative
movement
2. What do you think is meant when it is stated that "one cause for the failure
of cooperatives is due to non-patronage by coop members?
3. When the principle of subsidiarity is followed, what are the different
manifestations of this principle? Explain.
4. Cooperatives can promote social justice in Philippine society according to
the declared policy of the state on cooperatives. Why and how?
5. Why is the recognition of the nature of man neccessary in the success of the
cooperative movement?
6. The interest on capital in coops is limited but there is no such limitation in
corporation. Explain.
7. How is government intervention proscribed in the declared policies of the
government under the present Cooperative Code.
8. Cooperatives grant patronage refund, which is not present in corporations.
