I want to be able to solve in Cartesian coordinates, I think, since this is the very simplified form of a function which will contain many more terms.

Could someone walk me through how to maximize this 2-variable function wrt z? http://www.wolframalpha.com/input/?i=z+%3D100%2F%281%2B%28root+%28%28x-2%29%5E2+%2B+%28y-3%29%5E2%29%29%29+-+100%2F%281%2B%28root+%28%28x-2%29%5E2+%2B+%28y-3%29%5E2%29%29%5E2%29 I know the set of solutions will...

I have the summation (from i=0 to n) of (F_{t})(R) / (1+d)^i where F_{t} = (F_{t-1})[(R)(I_{p}) +(1-R)(I_{r})] (The F_{t-1} is referring to the value of F in the last period) I want to find the value of R that maximizes the summation. So must I take the partial derivative wrt R? How do I...
