Is there a way to get the analytical form to the root of this equation:
2 A e (-ArcTanh[smax/s0] + ArcTanh[(smax Cos[w ζ])/s0]) == F0
ζ is the variable to be solved and is bounded by (1/2 π / w, π / w).
Your form of equation is overpopulated with redundant constants slowing down computation. Rewrite and solve to get a simple concise form:
Get back to your original form:
@belisarius advice is good. But for someone who is new to Mathematica, then they should take advantage of the new suggestion bar in V9.
These are the steps to apply if you do not know the commands to use. By just typing the same line you showed, you will obtain the suggestion bar. By clicking on
In addition, Mathematica displays the command used and the solution automatically
