hi, i'm a bit confused, hope someone help me... here is my equations: for a = =CE=BBd / (=CE=BBd + =CE=BBin) P(0,0)= 1 / ( k + ((k-1) * (=CE=BBin/=CE=BCin)) + ((k-1) * (=CE=BBin/=CE=BCm)) + (a * ((1-a^(n-k))/(1-a))) + (a * ((1-a^(n-k))/(1-a)) * (=CE=BBin/=CE=BCin)) + (a * ((1-a^(n-k))/(1-a)) * (=CE=BBin/=CE=BCM)) + ((a^(n-k) * (=CE=BBd/=CE=BCD)) ) Availability (A) = P(0,0)*(k + (a * (1-a^(n-k)))) i want to find the optimal =CE=BBin which max. the availability.. is there any way to solve without giving any numerical values? i use D[A, =CE=BBin] but without numerical values i couldn't achieve any solution and i want to plot A-=CE=BBin from the equation, what should i do for it? best regards...
