The equation I have is:
$$A = B ( \exp(C x) - \exp(-Dx) )$$
How do I solve for $x$ given $A$, $B$, $C$, $D$?
I have no idea how. The only idea I have is that I could express these in terms of a taylor series, but is there a better way that I do not know? I could also generate $A$ based on known $B, C, D$ and for a given range of $x$ of finite steps, then find my particular $A$ of interest and see what $x$ was required. (I'm thinking that's a graphical way to attack this.) But it isn't very satisfying.
