 Author Comment/Response Rifi 09/26/12 09:58am In the beggining I'd like to say tah this is my first time with matematica so blease be gentle. ;) I'd like in this domain: ((700000*2*R/(Pi*(R^4-r^4)))==318)&&(R>0)&&(r>0)&&(R>r) Program would look for a minimum of function: pi*R^2-pi*r^2 I tried to do this but nothing came on my mind. :( I guess, the "smartest" thing i did was: [code]Minimize[Pi*(Solve[((700000*2*R/(Pi*(R^4 - r^4))) == 318) && (R > 0) && (r > 0) && (R > r), R])^2 - Pi*(Solve[((700000*2*R/(Pi*(R^4 - r^4))) == 318) && (R > 0) && (r > 0) && (R > r), r])^2, R][/code] Unfortunately nothing happened.
