Homework Equations


I have yet to figure out any relevant equations, but I do believe that the constraint equation for the optimization problem is the y=64-x^6 listed above.

The Attempt at a Solution


I am currently trying to figure out methods to begin my optimization process, such as configuring a basic area formula to optimize; however I'm not quite sure where to begin.

You should start with the equations of the lines through ##AC## and ##CB##. Handle the point ##C## as if you know it: ##C=(x_0,y_0)##. Also a diagram of the situation would help you a lot. In a third step, write the integrals you must solve to calculate the area. All as if ##C## was given. At then end, after the integration, you should get a single equation in the variables ##x_0,y_0## which you can minimize.

I tried doing that, but I ended up integrating constants after producing the equations.
 
Can you show us what you've done, so we can see where the difficulties lie?
This page https://www.physicsforums.com/help/latexhelp/ can help you type formulas.

Which equations did you use for the straight lines, when you've only given points?
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
