Hi everybody. I have this equation c=(m/b)(a-(F/b))exp(-btn/m)(1-exp(-bt/m))^2 where; a=0.14 m=4.3 F=1.88 n=integer (1-5000) t=0.1 c=2x[(n+1)t]-x[(n+2)t]-x[nt] --- the value for x at a particular n is obtained from a graph I have to solve for b. I have tried to solve this equation using Mathematica using the `Solve` command but there was a warning about the expression non in algebraic way. Is there anybody out there who have any idea what function I can use in Mathematica to solve this equation? It seems easy because the only unknown is b. But I am not familiar with Mathematica so I still can`t solve it. Thanks in advance.
