Minimum of the function

Given the following function


I would like to find a value c for which the above function is minimal.
Setting the above derivative to zero (with respect to c) should work, but I'm not sure how to handle
squares in a summation.

Re: Minimum of the function

The melee of terms in the summation is just to confuse you. Don't be sidetracked by it. Just focus on this question: If
(where
are real numbers) what can you say about
themselves?
