The swimming / running optimization problem: There was one final step in Wednesday's optimization problem that we didn't do in class.
We were looking for the absolute minimum of the function T, and we checked the critical number x=75;
but recall that when you have a closed interval, the absolute extrema may occur at one of the endpoints.
In our first two examples, this didn't matter because the range of possible values for width (in the farmer example) and radius (in the soup example) were open intervals;
we could make the width or radius very small but we could not have width=0 or radius=0 because we wouldn't have a field or soup can if we did.
However, in the swim / run problem, x could be 0 (swim straight across the river first) and x could be 300 (swim directly to the man).
So we have to check these endpoints and see if the value of T is smaller there than at x=75.
