In Problem 15 of Chapter 9, this equation was used to find the surface area of a cylinder with a conical base: 2V -+ xr csc 0 2 We can show by calculus that S is a minimum when the angle of the cone is given by 0= cos – 1(2/3). Use Solver to confirm that we did the differentiation correctly. How close is Solver's value to the expected one? Can you improve on this?
