By substituting into the given differential equation in Exercises 1 to 6, verify that the corresponding formula to the right gives one or more solutions to the differential equation. Then determine the arbitrary constant so that the differentiable function y(x) satisfies the given initial condition of the form y(a) = b and satisfies the given differential equation on an interval containing a. \frac{dy}{dx} = -\frac{x}{y}; y = \sqrt{a^2 - x^2}, |x| < a, y(1) = 4 y' + y = 0; y = Ke^{-x}, y(5) = 6

(II) Give focused discussion on the following questions. Make drawings and calculations where necessary. (The refractive index of water is 1.33.) (a) An inexperienced fisherman goes fishing in the morning, but a strong sun glare off the water surface blocks his view on the fishes. Can you help him solve this problem? What equipment would you recommend and describe the key features? Is there a best time of the day when it works the best? (15 points) (b) A diver in the water looks straight up and sees the fisherman's boat. But it appears to be compressed within a circle. This phenomenon is the so-called Snell's window (see picture on the right). Explain the physics behind it and estimate the viewing angle of the circle to the diver. (15 points)
