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.
