From two places equal of radio circular R It wants to build a buoy consists of two equal bass common cones

Determine the radius of Ia base when the volume of the buoy is maximum.

r=(sqrt of 6) R/3

Re: Max and min

I must confess I have little idea what you are asking. I am assuming a buoy is to be constructed by joining two cones at their bases, but other than that I have no idea what is going on.

well, what you said is the main idea
a buoy is something put ond the water on beaches as a limit so that people can not go further if they do not do that they can die

Yes, I understand that a buoy is used as a marker on the water, but it is the problem I don't understand. Can you provide a diagram?
 
Re: Max and min

from two pieces that are the same i mean equal of radius R , from these i want to built the buoy
there is no graph in my book
ahhh. the pieces are circular both
 

Thread 'What do you think of this new explanation of Zeta function?'

For original Zeta function, ζ(s)=1+1/2^s+1/3^s+1/4^s+... =1+e^(-slog2)+e^(-slog3)+e^(-slog4)+... , Re(s)>1 Riemann extended the Zeta function to the region where s≠1 using analytical extension. New Zeta function is in the form of contour integration, which appears simple but is actually more inconvenient to analyze than the original Zeta function. The original Zeta function already contains all the information about the distribution of prime numbers. So we only handle with original Zeta...
