Consider again the fish population from Example, where dP/dt = (1 − P/10)P − H(t) described the harvesting of a fish population and the time Was measured in months. The harvesting strategy was defined by the piecewise function

which modeled heavy harvesting in the first three months of each year, fighter harvesting during the remaining months of the year. The fish population rebounded in Example, but this is not always the case. Use the Keyboard Input box to help find the critical initial fish population that separates life from extinction.
