how can i solve 1/(F)^.5=2log((1.41x10^6(F)^.5)/2.51. I would like to know the "F" .I only can solve it in NumSolve menu. Can i solve it in program ??

Hi. 
I tried to solve it in main, but it seemed to me that the exact value cannot be given. If you enter the equation with the sysntax: solve(eq,var,guess value), it will solve it numerically, and very fast. Ex: solve(1/(F)^.5=2log((1.41x10^6(F)^.5)/2.51,F,1)) => x=0.05193....

Directly you can't use NumSolve in Main. But you van write a program (BASIC Program) to solve it (use newton-raphsone or other simillar methods)
