Example 3 presents us with yet another straight river, and we see the welcome return of the aforementioned Being of Unspecified Gender. Duration: 8:48

Hey, don't forget, before we proceed to the calculus, we need to consider the domain of our time equation. What is the smallest possible distance the BUG could land on the opposite bank, and what is the largest? Don't worry, that's not an optimization problem. Duration: 9:40

Finally, complete the Closed Interval Test by plugging the critical number and the endpoints back into the original time equation. Which value concludes the BUGS travels in record time? Duration: 2:12

Now it's your turn. Apply the optimization process to Example 4 to determine the minimum amount of material necessary to hold 1 liter of your favorite hearty soup. Yes, the problem asks to minimize cost, but doing so is based upon using the least amount of metal for your can.
