Hi Maria, try: Solve[f==14.4*((2/Sqrt[r^2+R^2])-1/r),r] what will give a pretty ugly formula. hope this helps, Daniel maria wrote: > Dear all, > I am new with mathematica.

I just want to express the function as r =.....*f. Is > this possible with mathematica. > Thank you. > -- Daniel Huber Metrohm Ltd.
